Physics 7B Equipotential lines, v.2.0 p. 1 NAME: _____________________ SECTION DAY/TIME: _____________________________ GSI: ___________________________ LAB PARTNERS: ____________________________ Equipotential lines and electric fields Introduction This lab gets at one of the most difficult concepts in the course: electric potential, and its relationship to electric fields and potential energy. The lab activities and associated questions can help you get a real-world feel for these concepts and their conceptual underpinnings. The hardest thing about potential, however, is to see how all this fits together. The activities below are designed to take only a portion of this period. We will take the rest of the time to continue with discussion section activities. Questions 1. In these pictures, the two conducting regions (marked in white) carry equal and opposite charges. What will the equipotential lines look like in each case? Remember, two points have the same potential if a charge would have the same potential energy at either point. Sketch your predictions here using dotted lines. + - - + + - + - Now pick two of the four configurations, and experimentally sketch the equipotential lines, using the procedure on the next page. You should do one; your partner the other. To check your other two predictions, you can look at the work done by other lab tables.
