Follow this physics lab tutorial to learn how to plot electric field and electric potential. Step-by-step instructions make it easy to understand the concepts, visualize results, and apply theory to ...

The electric potential at any point in space made by a point charge Q is presented by the formula given below. It is the electric potential energy per unit charge. The electric potential at any point ...

The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.

This video analyzes where the electric potential becomes zero for a system of two point charges. We examine different charge signs and magnitudes, explain how potential adds as a scalar, and determine ...
