Var (Noun)
Meaning
A unit of electrical power in an AC circuit equal to the power dissipated when 1 volt produces a current of 1 ampere.
Classification
Nouns denoting quantities and units of measure.
Examples
- The var unit is used to express reactive power in an alternating current circuit.
- A var is defined as the absolute value of inductive or capacitive power flowing through a circuit element.
- The volt-amperes of reactive power is abbreviated as var and is a unit of measurement.
- It takes 1000 vars to equal 1 kilovar in reactive AC power terms of measurement.
- In electrical terms, vars are used to measure the reactive power component of AC circuits.
