Definition of Voltage

By

Definition: The definition of voltage is the electromotive force or the electrical potential difference between two points in a circuit expressed in volts. The easier way to understand voltage or volts is to use a water analogy. Using a hose as an example, think of voltage as the amount of pressure forcing water through a garden hose. Electricity flows through devices in either Direct Current (DC) or Alternating Current (AC). For additional information, see the definition of current.
Also Known As: volts
Examples:
A stereo receiver operates on 120 volts AC (Alternating Current)
