What is Voltage?

Voltage is the electric potential difference between two points and is defined as the work done per unit charge to move a test charge between those two points. But how does all that relate to electricity? In this video, we'll show how electric charges can build up on surfaces, known as "static electricity," and how those charges can be used to define voltage. Obviously, a static electricity demonstration requires the creative use of balloons.
