Fold one end to use as a handle. A. Step 3: Add an extra bulb into the circuit loop. Wool is a conductive material, which means it readily gives away its electrons. You are going to measure the displacement of the hanging ball. A rod of plastic rubbed with fur or a rod of glass rubbed with silk will attract small pieces of paper and is said to be electrically charged. Test your understanding: Without using the simulations, predict the answers to these questions, then use the simulation to check your ideas. Repeat the demo using the sim with the charges on. Practice taking measurements and compare your readings with those of your lab partner until you are sure you can do them accurately. Uncategorized coulomb's law experiment lab report conclusion. 2. attachment_2. Question 1: When the balloon is rubbed on the sweater, what might happen? Coulomb's Law describes three properties of the electrical force: The force is inversely proportional to the square of the distance between the charges, and is directed along the straight line that connects their centers. When the balloon has been rubbed enough times to gain a sufficient negative charge, it will be attracted to the wall. When rubbed, a piece of amber can attract small objects like tiny pieces of paper. Objects of the same electric charge repel, and objects of opposite charges attract. 286 Comments Please sign inor registerto post comments. In an insulator (a material that does not conduct electricity), a charge cannot move very far (if at all). In the induction process of charging, a charged object is brought near to but not touching the electroscope. Arrange the objects in two categories according to their cha. Include in the discussion the vocabulary: charge transfer and electric attraction. If the humidity is high, as it is sometimes in the summer, the experiments are more difficult, and some may be impossible. The material losing electrons now has fewer electrons than normal and becomes positive. Nevertheless, a charged object will attract a neutral macroscopic object by the process of electrical polarization. This USB port seemed to have very high amperage, meaning it charged her phone quickly. The metal plate does not pick up this positive charge, even though it rests on the lucite. it will stay on it. c. What do you think would happen if you use 2 charges instead of one to make the puck Most electrons will go into the knob and down to the Static Electricity Evaporation Dissolving The three methods will be compared at the end of this lab report. Make sure that they understand that this is commonly called grounding. Turn down the variac and shut the power off. when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon's particles, on the force between them. USW00094728 if you use two of the same ones exactly opposite to each other, they would also cancel out and the puck would be stationary. For this experiment, I got the negative charges from the sweater for both balloons. Connect the 3-phase circuit as shown in gure 1.2. Definitely a returning customer. 1. The study of the Coulomb forces among arrangements of stationary charged particles is called electrostatics. Move the rod along and around the top so you touch as much of its surface to the metal of the electroscope as possible. b 1. Begin rubbing it with the fur. d. How would the arrows look if the puck was negative? each other. Estimating the charge of one . Please write answers direct on the PDF file. In this section, you will observe the induced polarization of a neutral insulator and the transfer of charge by contact. Say Discuss For a negative charge, when using the two different charges opposite to each other the puck would go twice as fast towards the negative charge puck. With this movement have come new types of applications and rapid advances in the technologies and techniques needed to fabricate the increasingly miniature devices that are literally changing our world. Cut 4 pieces of tape each about 10-cm-longh. Once a charge is Plot (by hand or with Excel) \(d\) versus \(1/r^2\). If the humidity is fairly low on the day of your lab, the experiments will proceed easily. (phet.colorado/en/simulation/john-travoltage). Great content here. In the conductor, electrons are free to move through the material, and some of them are repelled over to the opposite surface of the conductor, leaving the surface near the negative rod with a net positive charge. Each metal atom contributes one or two electrons that can move relatively freely through the material. c. Which way do you think the puck will move? Most of the common objects we deal with in the macroscopic (human-sized) world are electrically neutral. Write what you think is happening. Follow AMERICAN UNIVERSITY OF SCIENCE & TECHNOLOGY FACULTY OF ENGINEERING DEPARTMENT OF COMPUTER AND COMMUNICATIONS ENGINEERING CIRCUIT ANALYSIS 1 LAB CCE 201L Report # 2 DMM-Power Supplies-Soldering Techniques-Making PCBs Prepared by Daniel Khazaal Presented to Dr. Nashaat El Halabi February 26, 2016 Achrafieh Campus 2. Include in the discussion the vocabulary: charge transfer and electric attraction. Values of Thickness 2. Preparation At your lab station, you should have three disc-shaped objects mounted on long, insulating handles. They are different in the way that a gravitational field acts on a mass and electric field acts on charges. STATION Make, sure the tapes are sufficiently far so that they do not interfere. Try to estimate measurements to 0.2 mm. The force is proportional to the product of the magnitude of the charges. For reference purposes, according to the convention originally chosen by Benjamin Franklin, the lucite rods rubbed with silk become positively charged, and the rough plastic rods rubbed with cat's fur become negatively charged. placed on an insulator, it will remain at the same spot until it is neutralized. Reflect on your answer to #5, write down how your thinking has changed. Have a class So the balloons did move away from Recharge the lucite rod with silk. In this case, we can conclude that the charge increases (V), there is a greater strength of the Electric Field (V/m). determine the equation for the relationship. SET thevaluesofq 1 to-7 Candq 2 to10 C. 3. The purpose of this lab was to understand the idea of electrostatics AKA static electricity, and how electric charges interact with one another. repel, and objects of opposite charges attract. CONCLUSION. Why or why not? spreadsheet. Objects of the same electric cha. Discussion, Results and Conclusion Conclusion This lab aimed to show the effects of electrostatic forces between different charged objects. The experiment that was conducted to prove my theory started by getting all the negative charges Usually the lucite needs to be charged only once for the entire experiment. Electrostatic Lab Investigation #1: Materials: - fur - plastic rod -wool - balloon - electroscope Procedure: 1. Collect data by turning on Values & drag in the Tape Measure like in this image: The answers from #2 and #3 support the results from the investigation since the same rule applies that similar charges will repel each other and opposite charges will attract each other. Use several sentences and perhaps a diagram or two to explain the behavior of the charges in the electroscope. The USB was universal, providing 5 volts in any country you were in, and a small red LED next to her phone's screen told her the phone was successfully charging. This part uses the Charges and Fields simulation from PhET Interactive Simulations, Learning Goals: Students will be able to describe and draw models for common static slightly electrocuted. Entertainment & Pop Culture; Geography & Travel; Health & Medicine; Lifestyles & Social Issues; Literature; Philosophy & Religion; Politics, Law & Government Some positive charges in the wall will move towards the Observe what happens with the electroscope needle. This process extends to other objects and real world applications, such as the controlling of electrical cable manufacturing and application in areas such as a television depot station, where static electricity must be managed and accounted for to avoid disruptions. Electrons are being transferred from the balloon to the sweater. Charge the electrophorus lucite plate by rubbing it with silk. The balloons will move away from each other. The data does suggest. What do you predict for the answer? 3 1 m 18 V 12 V/m Lab Report #2 for the Electric Circuits 1 course. Record this explanation in your notes. The experiment that was conducted to prove my theory started by getting all the negative charges from the sweater then putting it up against the wall once it was filled with the negative charges. Set the metal plate aside. Two particles of the same charge exert a repulsive force on each other, and two particles of opposite charge exert an attractive force on each other. illustrates the direction of the field in a positive and negative charge. Put the sliding ball in, and make trial measurements of the inside edge of the sliding ball and the inside edge of the hanging ball. charges attract and acts along the line between the two point charges. The arrows on the puck are illustrating how both the positive and Write down "attract" or "repel" according to your observations. User Generated. Electric Circuits 1 lab report 1. the positive charges of the sweater instead of each other. Include in the discussion the vocabulary: electric repulsion; compare with charge Electrostatics - 1 Electrostatics PES 216 Report Objective (up to you this time) The purpose of this lab was to investigate the nature of electric charge: how different materials obtain different charges, how like and opposite charges react with one another, . then explore to develop your own ideas about electrical charge. Sweater will become electron deficient thus, making it have more positive charges. The little yellow E field sensors are like the The keynote speech delivered by Carl Sagan played a big r Our tutors provide high quality explanations & answers. The arrows would be opposite to what the picture displays. Take measurements, and record the diameter of the balls (by sighting on the scale). Negative charge on the sweater will move on to the balloon. Consequently, 3) Stick the "T" and the "B" tape to a surface, so that about 9 cm of the tapes are hanging freely in the air. (The purpose of the closed box is to minimize the effects of air currents. Why can you use either a positive charge or a negative charge to move the positively Talk about the similarities and TSG Consulting. Electric charge comes in two forms: positive and negative. InstructionsIn a two-page paper, identify the physics principles contained within the following scenario. c. Determine the relationship between amount of charge and the strength of the electric field After it touches the sliding ball, the hanging ball will pick up half the charge and be repelled away. Explore to develop your own ideas about electrical charge. Static Electricity Lab Report new Lab Report University University of North Carolina at Greensboro Course Genrl Physics Ii With Calc Lab (PHY 292L) Academic year2018/2019 Helpful? Later, other materials were found which exhibited this same behavior. b. You must use appropriate significant figures and scientific notation in your answers. If you use two of the same charges to move the puck, it would move twice as fast, if you use two If the humidity is extremely low, as is often the case in Southern California, you will probably not escape the lab without a direct experience with electrostatics! ScenarioMandy took a trip to Rome, Italy. However, if a neutral object is placed inside a strong electric field, the material may become polarized. PHY 2. Observe what happens with the neon tube. Equipment: Faraday Pail setup including ground plane and wire cage, charge sensor, two conducting spheres, high voltage electrostatic voltage source, computer with Enter the email address associated with your account, and we will email you a link to reset your password. Later, other materials were found which exhibited this same behavior. After completing these experiments, it was observed that like charges repel one another and opposite charges attract. The positive charges on the wall will move towards the balloon, while the negative charges will repel against each other. Instead, when you touch the metal plate, electrons from your body (attracted by the positive lucite plate) flow onto the metal plate. The fundamental concept in electrostatics is electrical charge. Title / Cover Sheet: use the provided cover sheet. 2. Studypool is not sponsored or endorsed by any college or university. (Do not confuse electrical polarization with the polarization of light, which is an entirely different phenomenon.). When you are asked to write your observations, please do so in a clear, complete manner. As shown in the demo below, the sweater is positive and the balloon attaches to the sweater due to the rubbing and the balloon essentially attracts to the electrons. https://phet.colorado.edu/sims/html/balloons-and-static-electricity/latest/balloons-and-static-electricity_en.html Charge laboratory: The lab will have two parts describing what is happening at both macro and atomic scales. electroscope. Basic Questions for Ohm's Law Lab Report Question: What is Variable DC supply? You can ameliorate this effect somewhat by shining a heat lamp on the insulators in the apparatus. force on the like charges farther away. If they are charged differently, they show attraction. The The experiment used a method known as titration to determine the amount of acetic acid in vinegar by percentage mass. Touch the pith balls with your finger to discharge them. This can happen when two non-conducting materials are rubbed together for example plastic and fur. Wool is a conductive material, which means it readily gives away its electrons. School. Step 2: Note down the reading on the ammeter and the voltage of the battery. An earlier FBI conclusion agreed with the lab origin theory with "moderate confidence," but other U.S. government agencies - as well as DoE itself - previously concluded there isn't enough information . Insert your data table and graph from your discussion. electric attraction. Metallic conductors allow the free flow of ions and electrons through a sample; and its conductivity decreases as the temperature increases.. Record and explain your results. (Refer to the theory section, if necessary.). Consequently, when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon's surface. In an insulator (a material A metal ball (C)charged with static electricity can be lowered into the pail on a nonconducting silk thread. where r is the distance between the two charges and k is called the proportionality constant and is One common demonstration performed with the electroscope involves the induction process of charging. b. Lab 1 - Electrostatics Lab's goal To investigate the electrostatic interaction between various objects. The metal plate is negatively charged by induction. Different materials have different desire for electrons; this is called electronegativity. During the few days after your assigned lab period: Meet with your lab partners to plot and/or reduce your data, to draw conclusions, and to the group lab report. (The heat lamp may help to minimize humidity near the pith balls.). iv. Most materials are electrically neutral they have an equal What do you predict for the answer? Materials: We conducted a comprehensive experiment that proved a valid existence of the relationship between equipotential lines and the electric field lines. What can we do to change some of the problems?Cite Plea 4.10 Graded Assignment: Resolving the Crime, Monroe Community College Statistics Worksheet. go twice as fast towards the negative charge puck. Below are 5 core components of a good conclusion for any scientific lab report: Restate the Experiment's Goals. Conclusion general unknown metal objective the projectile motion are many concepts of a lab report conclusion. Hold the plastic rod tightly.

If the needle has not fallen to 0 after five minutes, record an estimate of its angle at the five-minute mark. negative charges quickly left his body as he touched the doorknob as shown below. The charges tend to accumulate on the surface of the balloons. Touch his finger to the door knob to show Your body thus acts as an electrical ground. Rub Johns foot on the floor to demonstrate charge transfer. KVL states that in a closed loop the sum of the voltages of branches are equal to zero. Typically, after charging, the needle might be at 80. What do you predict for the answer? Therefore, to demonstrate the inverse \(r\)-squared dependence of Coulomb's Law, we need to measure the displacement as a function of the separation between the centers of the balls. PHY 2 Lynn University Electrostatics Lab Report . Are you in need of an additional source of income? Using the values from the experiment, we found that the slope of the line is 1.51. The side which the tape faces matters. When charge was transferred to the top, the gold leaves would become charged and repel each other. Provide details on what you need help with along with a budget and time limit. The flow of direct current in a circuit is only possible when the circuit is closed, however, if the circuit is open, the flow of current stops. 54 Comments Please sign inor registerto post comments. always steal electrons from things they come in contact with; others are. They were attracted to 4. Rub Johns foot on the floor to demonstrate charge transfer. A lab report is an account of an experiment and what was discovered during the experiment. Theory When objects are rubbed against each other they acquire electric charge. Direct current is a type of current that flows only in one direction. This process is called charging by friction. Your matched tutor provides personalized help according to your question details. A. You do not need to repeat the question. If you listen to a radio, then you are using Maxwell's research. Because the positive charge is not used up, the metal plate can be charged repeatedly by induction. Devise and execute an experiment to verify the dependence of the Coulomb force on the value of one of the charges. Therefore the balloon material ends up with an excess of electrons and becomes negatively charged, while the other (sweater) ends up with a deficiency of electrons and becomes positively charged. Once you rub the balloon to the sweater, it gathers electrons so that once you place the balloon Torque and j-s29029-17 non-precedential decision - the each contributing 50% to draw final lab partners:. Subject. The word electricity comes from the Greek word electron which means amber (a tree resin that 4 Pages. Record the results in your notes. If this is the case, you can try again next week. If a neutral material is placed inside a weak electric field, it will not experience a net force, USW00094728 law. Place the metal plate on the center of the lucite plate, and touch it with your finger. Is there any difference in the behavior of the needle compared to the results in procedure 6? If the needle falls to 0 in 15 seconds or so, as it does on some summer days, you will probably have difficulty completing the experiments, even with the help of the heat lamp. In this section, you will observe the characteristics of the two types of charges, and verify experimentally that opposite charges attract and like charges repel. It depicts how the gravitational attraction force for small objects is insignificant when compared to electrostatic charge. If high-humidity conditions prevent you from completing certain parts, you may try them again next week with the Van de Graaff experiments. A. Figure 2. Thus, the polarized material will experience a net attractive force. The charged particles which make up the universe come in three kinds: positive, negative, and neutral. If you have done everything correctly, the electroscope should have a permanent deflection. You may use the stopwatch function of your wristwatch. Slide 1 of 4. attachment_1. hockey puck but they are on a high friction surface, so they stay in place allowing for When you rub a ruler with different materials, it can cause it to gain or lose static electricity depending on its electrical conductivity. This experiment consists of many short demonstrations in electrostatics. You can stack charges on top of one another 1. You can do this with the Recharge the metal plate, and actually touch it to the top of the electroscope. Write observations with drawings of (You may feel a slight shock.). What happens? discussion. What is the exponent of the \(r\)-dependence of the force? (transfer of charge, induction, attraction, repulsion, and grounding). Bring the lucite rod near (but not touching) the top of the electroscope, so that the electroscope is deflected. Open phet.colorado/sims/html/balloons-and-static-electricity/latest/balloons-and- Assist the Continuous Improvement Manager on data collection, analysis, and compilation as it relates to LEAN projects throughout . Describe the materials and fabrics that you found: Does it matter which side faces which side? different fabrics, such as cotton, silk and wool. These equations will verify this statement: -Vs+Vr1+Vr2=0-5v+1. Record the results your notes. In an electric field, the system can be repulsive or attractive, whereas in a gravitational field, the systems are just attractive in accordance to its specific mass in its region. Hi, I need somehelp with General Chemistry class question. Astronomy Lab due. Question 3: What do you think the balloons will do? Protons Distance (m) Voltage (V), Volts/Meter
