VOLT AMPERE Meaning and
Definition
-
A volt ampere, commonly abbreviated as VA, refers to a unit used in electrical engineering to measure the apparent power in an electrical circuit or system. It is a combination of two primary units of electrical measurement: volts and amperes.
Volts, denoted as V, quantify the electromotive force or potential difference between two points in a circuit. It represents the energy per unit charge that an electrical source or device can provide or consume. Amperes, denoted as A, measure the current flowing in a circuit, which is the rate at which charge flows through a conductor.
The concept of volt amperes arises when considering the volt-ampere product, which is the mathematical product of volts and amperes. While a volt ampere is often used interchangeably with the watt (W), there is a distinction between the two. Watts measure the real power in an electrical system, taking into account the actual work done or energy consumed, whereas VA represents the apparent power which includes both the real power and the reactive power.
Reactive power refers to the power consumed or produced by devices such as inductors and capacitors in an alternating current (AC) system. In situations when reactive power is present, the apparent power (VA) can be greater than the real power (W).
In summary, a volt ampere is a unit used to measure the apparent power in an electrical circuit, calculated by multiplying the voltage (V) by the current (A). It encompasses both the real power (W) and the reactive power, providing a comprehensive understanding of power consumption or production.

Etymology of VOLT AMPERE
The word "volt ampere" is derived from the combination of two units of measurement: the volt and the ampere.
The term "volt" is named after the Italian physicist Alessandro Volta, who invented the electric battery. The word "ampere" is named after the French physicist André-Marie Ampère, who made significant contributions to the understanding of electromagnetism.
When electrical current flows through a circuit, it is measured in amperes (A), which represents the rate at which electric charge flows. Voltage, on the other hand, is the potential difference or electric potential energy per unit charge. It is measured in volts (V).
So, when the terms "volt" and "ampere" are combined into "volt ampere", it represents the product of voltage and current, resulting in a unit of electrical power.
