Electric Fields and Electric Potential Name: Daquan Sisco_________________ Date: __1/10/09____________ Name: ____________________________ Lab Sect.: __________ Name: ____________________________ Lab Instructor: ______________________ Lab Activity 1: Visualizing the electric potential created by a dipole ( Warning: If you are using the lab template, you will need to save your figures to the desktop and then insert them into your lab report. Cutting and pasting from the EMField program can result in an error and a loss of any unsaved work!) Q1. Use the program to make a plot that shows equipotentials for the electric dipole with the following values: V = −3.2 V, −1.5 V, −0.7 V, −0.3 V, 0 V, +0.3 V, +0.7 V, +1.5 V, +3.2 V. (Do not worry about matching these values exactly; try to get as close as you reasonably can.) In this plot, also show a few electric field lines. Print this figure and include it with your report. Now, refer to your equipotential and electric field line plot, as well as to the exercises you carried out above, and answer the following questions. Q2. Do you notice any obvious geometrical relationship between equipotentials and electric field lines? Describe this relationship and why it makes sense. (Think about the direction of the electric field and the work done in moving a charge along an equipotential.) The change in equipotential is equal to the integral of the electric field times the change in
