Voltage

Jump to navigation Jump to search

Voltage is a measure of the potential difference (PD) in the electricity between two points in a circuit and is measured in Volts (V). The electrons entering a device have more energy than those leaving it, this difference is the voltage. A higher voltage means that the current is transferring more energy to that device.
