What is electrical voltage?

Electrical voltage represents potential energy per unit of charge in an electrical system. Electrical voltage describes the force that pushes electric charges (such as electrons) to move through an electrical circuit. High voltage indicates that there is a lot of potential energy per unit of charge, while low voltage indicates that there is little potential energy per unit of charge.

Simply put; if you think of an electrical circuit as a water pipe, electrical voltage can be compared to the pressure in the pipe. High voltage indicates high pressure, while low voltage indicates low pressure.

What is electrical voltage measured in?

Electrical voltage is measured in volts (V). For example, batteries can have electrical voltages ranging from a few volts to several hundred volts, depending on size and type.
