This is equipotential surface plotting lab. those are pre lab questions 1;2;4;5 are almost same. We used 5 V through out lab.

1. Place the tip of the red probe on the black (reference) electrode. What is the reading on the multimeter? Why?

2. Place the tip of the red probe on the opposite electrode. What is the reading on the multimeter? Why?

3. Are the equipotential lines as you expected? Is there any two equipotential lines crossing each other?

4. Place the tip of the red probe on the black (reference) electrode. What is the reading on the multimeter? Place the probe at different points on the line. Do they read the same voltage on the multimeter?

5. Place the tip of the red probe on the opposite electrode. What is the reading on the multimeter? Place the probe at different points on the line. Do they read the same voltage on the multimeter?
