Voltage
by the_admin
Voltage (potential difference): The voltage between two points in an electrical circuit is a measure of the potential difference or the force, that is pushing electrons between these two points. It is analogous to water pressure in a water system. Voltage is measured in volts and is directly proportional to the current and resistance of a circuit: V=IR, where V = potential difference in volts, I = current in amperes (amps) and R = resistance in ohms. This is Ohm’s law.
