Volt

Definition

The volt is the SI derived unit of electric potential, electric potential difference, and electromotive force. It is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power.

History/Origin

Named after Italian physicist Alessandro Volta (1745-1827), who invented the voltaic pile, the first chemical battery. The volt was officially adopted as the unit of electric potential in 1881.

Current Use

Widely used in electrical engineering, electronics, and physics. Essential for measuring voltage in circuits, batteries, power supplies, and electrical systems. Standard unit in all electrical calculations and measurements.

Watt per Ampere

W/A

Definition

A derived unit of electric potential equal to one volt. Represents the ratio of power (watt) to current (ampere), which by definition equals one volt.

History/Origin

This unit arises from the fundamental relationship between power, voltage, and current in electrical circuits (P = V × I). It provides an alternative way to express voltage using basic electrical quantities.

Current Use

Used in electrical engineering when analyzing power systems and circuit relationships. Helpful for understanding the fundamental connection between voltage, current, and power in electrical circuits.
