A. Parallel Plate (one plate positive, one negative) To simulate a plate just make a line of charges right next to each other. Make the plates fairly long. When drawing the E-field lines just concentrate on the region between the plates. 11 IE B. Two Point (1 positive and 1 negative charge, equal value) TV 2 C. Point and plate (make the single point positive and the plate negative). Match the charges (so if you use 10 charges to make the plate, stack 10 charges on top of each other for the point). I! D. Faraday Ice Pail (point and "bucket") Again, match the charges so that the point has as many charges as the bucket. 3 w Answer the following question in your conclusion: For the parallel plate, the two point and point and plate configurations look carefully at the distance between adjacent equipotential lines on a line down the center between the plates. Explain why the electric field strength is constant (or not) by looking at the potential gradient (AVI AX) and its relationship to E-field strength.
Now you will set up a series of different charge distributions (shown below), and for each distribution you will: 1. Use the potential meter to draw enough equipotential lines to create a map that fills the screen. The exact voltage of each line is not important here - we're just looking for the overall shapes of the equipotential lines. Add more equipotential lines in areas where the shape of the lines is changing rapidly. 2. Check the "Voltage" box to illustrate the signs of the voltages. 3. For each map use the equipotential lines to help you draw in the E-field lines for that setup. Remember: • E-field lines are always perpendicular to the equipotential lines, • should never cross themselves and, • you should indicate the direction of your E-field lines. Use the drawing feature in Word (or any other graphics software you have) to draw in some representative E-field lines. Draw enough lines so that you give a good idea of the overall E-field. If you can't do this in software, or if you prefer, make a hand drawn sketch of the each configuration and scan them. Be sure to show and label the equipotential and E-field lines.
