1. Describe the map of equipotential lines obtained when the electrodes on the conducting sheet are two point sources of equal and opposite magnitude. 

2. Describe the map of equipotential lines obtained when the electrodes on the conducting sheet are two parallel plates of equal and opposite charges. What happens to the equipotential lines just outside the parallel plates? 

3. Describe the electric field lines that were drawn on the map of equipotential lines for (a) the two point sources and (b) the parallel plate configuration. How are the equipotential lines related to the electric field lines?

4. When the movable probe touches a point on the conducting sheet and the galvanometer needle deflects away from zero, explain why the current reading is not zero. 

5. When the movable probe touches a point on the conducting sheet and the galvanometer reading is zero, explain why this point has a potential VM that is equal to that of the reference point VR
