Energy, Voltage, and Equipotentials
So, what units is electric potential measured in? Volts! You’ve probably heard the term "voltage" before since it is something that most people encounter daily. The outlets you plug into are rated at 120 V (for the United States) and 220 V (for Europe and elsewhere). Though these concepts are not exactly the same, the same terminology is commonly used (you’ll learn why they are not the same soon!). Use the following illustrations to explore these concepts graphically.

Another important concept to explore is that of moving a particle along a line of equal electric potential energy—equipotential lines. Use the following illustration to explore work and equipotentials.

It is important to realize that these lines of equipotential are NOT the same as electric field lines. What is the difference? Use the following explorations to investigate the differences.
