Day 91: Visualizing Equipotential Lines

We should have done this lab yesterday. Today started with a struggle to understand how to draw equipotential lines and how equipotential lines and electric field lines interrelate. (We quickly understood that the unit for electric field strength, newtons per coulomb, were equivalent to volts per meter, but we had no idea why that was important.) It was tough. But, once we got to lab, the equipotential lines made a lot more sense.
