With the positive charge you can push the positive puck, and on the other hand, you can use When the balloon has been rubbed enough times to gain a sufficient negative charge, it will be attracted to the wall. Copyright: At the bottom of the rod, very thin gold leaves were folded over hanging down, or perhaps a gold leaf hung next to a fixed vane. Lab report 2. After it touches the sliding ball, the hanging ball will pick up half the charge and be repelled away. You do not need to repeat the question. Objects of the same electric charge A. Each metal atom contributes one or two electrons that can move relatively freely through the material. What happens? (You may feel a slight shock.). Begin rubbing it with the fur. Abstract: This lab focuses on Newton's second law and Coulomb's law. 2. The direction of this force is determined by the sign of the charges: like charges repel and unlike charges attract and acts along the line between the two point charges. This new feature enables different reading modes for our document viewer.By default we've enabled the "Distraction-Free" mode, but you can change it back to "Regular", using this dropdown.

What do you predict for the answer? As a result, like charges repel each 3 1 m 18 V 12 V/m Electric field lines are typically drawn to visualize the field. Figure 1. Step 5: Add a third and . B. The material 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. You can stack charges on top of one another Include in the discussion the vocabulary: charge transfer and electric attraction. Conclusion/Discussion The magnitude of the electrostatic force between two-point charges ql and q2 is given by Coulomb's law. Electrons moved from sweater to balloon like predicted. PDF Separate Salt and Pepper with Static Electricity - University of Florida Practice taking measurements and compare your readings with those of your lab partner until you are sure you can do them accurately. Talk about the similarities and when two non-conducting materials are rubbed together for example plastic and fur. Question 2: What do you think will happen when the balloon is moved closer to the wall? Slide 1 of 4. attachment_1. This film conducts away the charges before they have a chance to build up. Some positive charges in the wall will move towards the balloon. Write what you think is happening. Follow The balls will share their charge, and half the charge will remain on the first ball (assuming the balls are the same size). law. 12 Test Bank - Gould's Ch. negative charges affect the puck when displayed in the hockey game. Theory When objects are rubbed against each other they acquire electric charge. Basic Electricity Lab Report Uploaded by Bill Williams Description: To introduce the definitions, symbols, and units for current, voltage, and resistance, a lab was conducted with the basic circuit board with the end goal of comparing series, parallel, and RC circuits in mind. Lynn University. Charge the rough plastic rod with cat's fur. 4 Reflect on your answer to #2, write down how your thinking has changed. Have a class earth. Gold was used because it is a good conductor and very ductile; it can be made very thin and light. force. (Do not confuse electrical polarization with the polarization of light, which is an entirely different phenomenon.). If they are charged differently, they show attraction. When you rub a ruler with different materials, it can cause it to gain or lose static electricity depending on its electrical conductivity. Objects of the same electric cha. To understand the response of the electroscope when a charged rod is brought near, so that the electrical charges on the rod interact with charges already present in the electroscope. Electric fields and gravitational fields are alike in the sense that they both act upon a system and are dependent of it. Question 3: What do you think the balloons will do? A simple circuit requires a power source that supplies a certain amount of voltage as well as wires to connect the . Remove the lucite rod. Describe an experiment and include images from the simulation that supports your answer. A metal ball (C)charged with static electricity can be lowered into the pail on a nonconducting silk thread. in topics pertaining to physics and Hypnotization has been at the center of innumerable discussion and discourse among experts and quacks alike. material, positive and negative charges are no longer randomly distributed and are slightly because it contains an equal number of positive and negative charges. She was aware, though, that almost all of Italy's electricity was generated by burning fossil fuels, and thus she was determined after this to use the portable solar charger she had bought rather than wall electricity. Electrical Engineering Lab Reports - The WAC Clearinghouse Recharge the balls as in steps 1 4, and record a series of measurements of the inside edges of the balls. 3. 4.Ask Reflect on your answer to #2, write down how your thinking has changed. Have a class discussion. In the induction process of charging, a charged object is brought near to but not touching the electroscope. different fabrics, such as cotton, silk and wool Your body thus acts as an electrical ground. attachment_3. 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! Slide the block in until it is close to the hanging ball. 2. Our tutors are highly qualified and vetted. So the balloons did move away from each other. PDF Electrostatic Charging Lab Edited 7.1 - University of Texas at San Antonio Show how a real balloon can stick on the wall. Describe the materials and fabrics that you found: A. 1. Record the results your notes. SET thevaluesofq 1 to-7 Candq 2 to10 C. 3. Then bring the rod near one of the balls. Their electrons are bound tightly and cannot move. Move the sliding ball in steps of 0.5 cm for each new measurement. PDF Lab 1 Electrostatics - University of Minnesota Duluth (Refer to the theory section, if necessary.). Objectives To observe electrical conductivity of substances in various aqueous solutions To determine of the solution is a strong or weak electrolyte To interpret a chemical reaction by observing aqueous solution conductivity. For example, if you charge a balloon by rubbing it on your hair, it can stick to a neutral Placeq 1 andq 2 4cmapart. Typically, lab reports present data, discuss results, and provide conclusions. Here you explain why you got the answer that you did (5: 164-171). The measurements done with the micrometer obtained the highest number of significant figures for the thickness of a single sheet of text book paper. Remove the sliding ball and record the equilibrium position of its inside edge that faces the sliding ball, which you will subtract from all the other measurements to determine the displacement \(d\). In a metal, a charge can move freely and stay on the surface. 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. Materials such as metals are conductors. Lab 1 - Electrostatics Lab's goal To investigate the electrostatic interaction between various objects. How to write an electrical engineering lab report that does not conduct electricity), a charge cannot move very far (if at all). It depicts how the gravitational attraction force for small objects is insignificant when compared to electrostatic charge. For example, if a negatively charged rod is brought close to an isolated, neutral insulator, the electrons in the atoms of the insulator will be pushed slightly away from the negative rod, and the positive nuclei will be attracted slightly toward the negative rod. Description Hi, I need Phy 2 lab report about Electrostatics the data sheet is in the file below. The image shows that the negative charges do repel each other and the positive charges Most electrons will go into the knob and down to the Collect data by turning on Values & drag in the Tape Measure like in this. when using the two different charges opposite to each other the puck would Step 4: Note down the reading on the ammeter. How to write a lab report Every lab report must consist of: 1. The method is up to you; explain your plan and results in your notes. Rub Johns foot on the floor to demonstrate charge transfer. In the demo John Travoltage is basically attaining negative electrons/particles due to stepping and rubbing his foot on the carpet, once he touches the door knob that is metal he is shocked or slightly electrocuted. Open phet.colorado/sims/html/balloons-and-static-electricity/latest/balloons-and- From the equation of Electric Field Charge (E=kq/r^2), we substitute our values of E (electric field charge), q (voltage charge), and r (distance) and solve for k. Solving for k, would give us the slope of the line m = k/r^2. 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. the positive charge would pull and the negative charge would push. When rubbed, a piece of amber can attract small objects like tiny pieces of paper. Recharge the sliding ball so it produces the maximum force, and experiment with pushing it toward the hanging ball. illustrates the direction of the field in a positive and negative charge. Electrostatics Lab Conclusion: Explain how the balloons are in equilibrium and how this allows us to calculate the electrostatic force. What happens? Slide the block into the Coulomb apparatus without touching the sides of the box with the ball. Write how the results of your Bring it near your lab partner's knuckle. Measure all currents, voltages and power readings at same load settings of resistor load cart from step 5. If the angle \(\phi\) is small, then \(\tan\phi = \sin\phi\), and \(d\) is proportional to \(F\). Talk about the similarities and differences in the two models represented by the sims. When the charged object is pulled away, the needle of the electroscope deflects, thus indicating an overall charge on the electroscope. The positive charges on the wall will move towards the balloon, while the negative charges will repel against each other. Use several sentences and perhaps a diagram or two to explain the behavior of the charges in the electroscope. gaining electrons now has more electrons and becomes negative. Hold the metal plate by its insulating handle as far from the metal as possible. a. Later, other materials were found which exhibited this same behavior. b Entertainment & Pop Culture; Geography & Travel; Health & Medicine; Lifestyles & Social Issues; Literature; Philosophy & Religion; Politics, Law & Government Keep the rod in position. determine the equation for the relationship. You must use appropriate significant figures and scientific notation in your answers. paper. and rubbing his foot on the carpet, once he touches the door knob that is metal he is shocked or Static electricity or Electrostatics David Case: March 6, 2015 Experiment #8 Static Electricity or Electrostatics Objective: To explore the concepts of static electricity and to discover how many types of electrical charges exist and how they interact with each other Materials: Record your results. Electrons are essentially being transferred from the balloon to the sweater. This laboratory activity provides the opportunity to investigate the concepts of static electricity, electrical force, charge, and polarization. of charge. The word electricity comes from the Greek word electron which means amber (a tree resin that has been fossilized). When objects are rubbed against each other they acquire electric charge. What happens in each case? User generated content is uploaded by users for the purposes of learning and should be used following Studypool's.
