Lab 1 - Electric Field and Electric Potential Introduction Physicists use the concept of a field to explain the interaction of particles or bodies through space, i.e., the "action-at-a-distance" force between two bodies that are not in physical contact.The earth modifies the surrounding space such that any body with mass, such as the moon, is attracted to it. Discuss the methods used. device used for producing high voltages and creating static electricity. A. However, if a neutral object Electrons will actually move along this path to the ground. (Do not confuse electrical polarization with the polarization of light, which is an entirely different phenomenon.). 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 Ohm's Law Lab Report [With Graph, Observations and Verification] Critique the lab and describe opportunities for further / future work. KCL states that the current entering a node is equal to the current leaving it. your observation with captured images from the simulation. spreadsheet. Remove the sliding ball, and recheck the equilibrium position of the inside edge of the hanging ball. The answers from #2 and #3 support the results from the investigation since the Lab 1.Electrostatics Goals To understand and verify the behavior of the two kinds of charge, denoted "positive" and "negative", respectively. has been fossilized). The magnitude of the electrostatic force between two-point charges ql and q 2 is given by Coulomb's (Sometimes it is necessary to touch different parts of the rod to the balls.) In this simulation, a little different model is used. Our best tutors earn over $7,500 each month! Berea, Kentucky, United States. 3. You can ameliorate this effect somewhat by shining a heat lamp on the insulators in the apparatus. 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. PDF Lab 1: Electrostatics - University of Michigan The old electroscopes consisted of a box or cylinder with a front glass wall so the experimenter could look inside, and an insulating top through which a conducting rod with a ball or disk (called an electrode) on top entered the box. Lab 1 - Electrostatics Lab's goal To investigate the electrostatic interaction between various objects. Objects of the same electric charge Studypool is not sponsored or endorsed by any college or university. For this experiment, I got the negative charges from the sweater for both balloons. Rub the lucite rod vigorously with the silk cloth. In an insulator (a material that does not conduct electricity), a charge cannot move very far (if at all). A metal ball (C)charged with static electricity can be lowered into the pail on a nonconducting silk thread. PHY 2 Lynn University Electrostatics Lab Report . The hanging ball should be at the same height as the sliding ball (i.e., the top of the mirrored scale should pass behind the center of the hanging pith ball, as in Figure 12 below).
