Charge the rough plastic rod with cat's fur. The hanging ball should be centered on a line with the sliding balls. surface. When the charged object is pulled away, the needle of the electroscope deflects, thus indicating an overall charge on the electroscope. The negative charges quickly left his body as he touched the doorknob as shown below. There are 3 types of metals for electricity conducting: metallic conductor, semiconductor, and superconductor. Title / Cover Sheet: use the provided cover sheet. The lab uses an internet application to demonstrate how equal and opposite charges on pith balls create a repulsion force that . Electric field lines are typically drawn to visualize the field. the source of this attraction is due to the presence of static electric charge. They are composed of atoms that consist of negatively charged electrons moving in quantum motion around a positively charged nucleus. Write how the results of your As a result, like charges repel each other and unlike charges attract each other. Then we will utilize two classic electrostatic devices the electrophorus and the Hard rubber rods, which are also commonly used, become negatively charged. Performing experiments and writing lab reports provide hands-on experiences with engineering concepts and devices. Later, other materials were found which exhibited this same behavior. USW00094728 Use Google Spreadsheet to document your data, graph, and Static Electricity Experiment Introduction The purpose of this experiment is to separate salt and pepper by using static electricity. The current should be read on the 300 mA (or lower) scale. Here you explain why you got the answer that you did (5: 164-171). Labs goal This can happen However, it is known that the making and breaking of contact between the two materials transfers the charge. Fold one end to use as a handle. For example, if you charge a balloon by rubbing it on your hair, it can stick to a neutral wall. 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. What happens? Test your understanding: Without using the simulations, predict the answers to these questions, then use the simulation to check your ideas. The image shows that the negative charges do repel each other and the positive charges remained. b Our best tutors earn over $7,500 each month! PURPOSE OF THIS ASSIGNMENT: To improve your scientific literacy and critical thinking Inside a polarized material, positive and negative charges are no longer randomly distributed and are slightly separated (positive on one side, negative on the other). What happens? Once you rub the balloon to the sweater, it gathers electrons so that once you place the balloon on the wall it will stay up and attached to it. 5 1 m 30 V 20 V/m, Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01. (The purpose of the closed box is to minimize the effects of air currents. The material losing electrons now has fewer electrons than normal and becomes positive. Do not bring the heat lamp too close, or the insulators will be melted. A neutral particle is not affected by electrical forces. The arrows on the puck are illustrating how both the positive and A modern electroscope such as the one used in your experiments consists of a fixed insulated vane, to which is attached a delicately balanced movable vane or needle. Repeat the procedure until you have experienced several sparks. Wool is a conductive material, which means it readily gives away its electrons. What happens in each case? Answer: A variable DC (direct current) supply provides variable output voltages. Is Coulomb's Law verified? Hit RESET to do this several times. Say Discuss 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 A. A mirrored scale permits you to determine the position of the balls. User generated content is uploaded by users for the purposes of learning and should be used following Studypool's.

Wool is a conductive material, which means it readily gives away its electrons. Record the results in your notes. attachment_2. Once a charge is Arrange the objects in two categories according to their cha. You do not need to repeat the question. Keep the rod in position. USW00094728 increases. TSG Consulting. You do not need to measure the position of its center, but will record the position of its inside edge. Once again, recharge the metal plate. it will stay on it. 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. In an insulator (a material Connect the 3-phase circuit as shown in gure 1.2. i. Later, other materials were found which exhibited this same behavior. Both the negative and positive charges have the same pull/push strength that can affect Electrons carry negative charge and protons carry positive charge. Explore to develop your own ideas about electrical charge. Most materials are electrically neutral they have an equal number of positive and negative charges (thus an equal number of protons and electrons). For a negative charge, In this simulation, a little different model is used. Objects of the same electric cha. Our verified tutors can answer all questions, from basicmathto advanced rocket science! The Essay on Formal lab report on ionic and covalent compounds. 12 Test Bank - Gould's Ch. of Physics & Astronomy Modified from: RealTime Physics P. Laws, D. Sokoloff, R. Thornton General Physics Part B and University of VA Physics Labs: S. Thornton Triboelectricity First, you must move some electrons around to produce a net electric charge. For a positive charge, the field is directed outward from the charge (figure 1a). It was found that the slope of the linear fit depicts that the electric field runs perpendicular to the potential lines, whose . The positive charges on the wall will move towards the balloon, while the negative charges will, What do you predict for the answer? Recharge the metal plate by placing it back on the lucite, touching the lucite, and then lifting the plate off with its insulating handle. Record this explanation in your notes. User Generated. with your partner what is happening when he touches the knob. Repeat the demo several times. The conductor has been polarized, and will now be attracted to the charged rod. Does it matter which side faces which side? Record and explain your results. If they are charged differently, they show attraction. Experiment Title: Chemical Equilibrium and Le Chateliers Principle. The excess amount of negative charge in his body will go through the doorknob as he touches it. The balls will share their charge, and half the charge will remain on the first ball (assuming the balls are the same size). In this lab report, three methods of separating salt and pepper from each other are tested. Hit RESET to do this several times. Use a little whipping motion at the end of the rubbing. 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. Login projectile motion refers to design and light. If high-humidity conditions prevent you from completing certain parts, you may try them again next week with the Van de Graaff experiments. Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. Recharge the balls as in steps 1 4, and record a series of measurements of the inside edges of the balls. Investigate to check your answers from #2 and #3. 4 Pages. Nevertheless, a charged object will attract a neutral macroscopic object by the process of electrical polarization. The arrows would be opposite to what the picture displays. You can change the charge on the sliding ball by factors of two, by touching it to the other uncharged sliding ball (ground it with your finger first). KCL states that the current entering a node is equal to the current leaving it. Bring it near your lab partner's knuckle. In this section, you will observe the induced polarization of a neutral insulator and the transfer of charge by contact. game. Most materials are electrically neutral they have an equal what happens and then repeat the demo. Use several sentences and perhaps a diagram or two to explain the behavior of the charges in the electroscope. Begin rubbing it with the fur. clear adhesive tape, Assist the Continuous Improvement Manager on data collection, analysis, and compilation as it relates to LEAN projects throughout . (transfer of charge, induction, attraction, repulsion, and grounding). 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. Preparation At your lab station, you should have three disc-shaped objects mounted on long, insulating handles. Rub the rough plastic rod with cat's fur, and bring this rod near the lucite rod in the stirrup. USW00094728 If so, how do you account for the difference? You can record and graph data in Excel or by hand (although if you work by hand, you will lose the opportunity for 2 mills of additional credit below). Consequently, Stuck on a homework question? I think that the balloons will repel each other because they are both negative and do not attract each other. of charge. This is explained by the like charges repel principle. 10 Lab 1: Electrostatics Vanderbilt University, Dept. Does anything need to be held constant? Look in through the side plastic window. In this section, you charged the lucite plate by rubbing it at the beginning, and were then able to charge the metal plate repeatedly. discussion. Electrostatics, as the name implies, is the study of stationary electric charges. 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. Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday that demonstrates the effect of electrostatic induction on a conducting container. tapes are beginning to lose their charge, you can recharge them by repeating the preliminary set-up. The little yellow E field sensors are like the These equations will verify this statement: -Vs+Vr1+Vr2=0-5v+1. Aug 2021 - Dec 20215 months. (V/m) The negatively charged Physics Lab Report. SET thevaluesofq 1 to-7 Candq 2 to10 C. 3. 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. 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. However, if a neutral object A neutral balloon will gain electrons from the sweater. Practice taking measurements and compare your readings with those of your lab partner until you are sure you can do them accurately. (Do not confuse electrical polarization with the polarization of light, which is an entirely different phenomenon.). investigation support or change your ideas. This can happen when two non-conducting materials are rubbed together for example plastic and fur. material losing electrons now has fewer electrons than normal and becomes positive. Explore to develop your own ideas about electrical 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.
