In this introductory physics laboratory experiment, we map the potentials around electrodes in simple geometries: two oppositely charged points, two concentric rings, and a point inside a ring. The potentials are measured on grids that enable later analysis to find the equipotential lines. From those, the electric field can be inferred. This is one of a sequence of videos for students to use who are taking physics laboratory classes online.
