var

A unit of electrical power in an AC circuit equal to the power dissipated when 1 volt produces a current of 1 ampere.

• 🇵🇹Unidade de potência elétrica em circuitos de corrente alternada, igual à potência dissipada quando a tensão é de 1 volt e a corrente é de 1 ampère; também chamada de volt-ampère reativo.

1. Unit of reactive power C1 formal scientific

   A unit of electrical power in an alternating current (AC) circuit, equal to the power dissipated when one volt produces a current of one ampere, used to measure reactive power.

   • The generator supplies 500 vars of reactive power to the grid.
   • Engineers measured the circuit's reactive power in vars.
   • The var rating of the capacitor bank is crucial for power factor correction.
