Voltage (V)

Definition

Voltage (V) is the measure of voltage potential, in volts.

Detailed Explanation

Voltage, given the symbol V, is the measure of electrical potential, expressed in the unit volts. It quantifies the electric pressure, or potential difference, between two points in a circuit, the force that drives current through a conductor when a circuit is connected. Expressed in volts, voltage is one of the fundamental quantities used to describe and rate electrical circuits and cable.

Because voltage is the pressure that pushes current, its value in volts determines how cable must be rated and insulated. A cable's voltage rating indicates the voltage its insulation can safely withstand in service, so the voltage present in a circuit guides cable selection.

In commercial and industrial systems, voltage in volts defines the operating conditions of circuits and the ratings cable must meet. Recognizing the measure and its symbol helps in interpreting specifications.
