Voltage

maker

Voltage is the electric potential difference between two points within an electric field, expressed in volts (V).

expanded

Voltage represents the condition that causes electric charges to flow in a circuit, measured in volts (V). It is an essential parameter in designing and assessing electrical circuits, influencing components' performance and safety requirements. Understanding voltage is crucial for applications such as power supply design and electronic device functionality.

examples

In a household power supply, the standard voltage is 230 V (120 V in the U.S.).

Voltage used in residential electrical systems to operate appliances and devices.

A 12 V battery used in automobiles.

Commonly provides power to start the engine and operate electrical systems within vehicles.
