What does volt ampere measure?

Volt ampere (V*A) is the unit of apparent power in AC circuits, calculated as the product of root-mean-square voltage and current, representing total delivered power regardless of power factor.

Why convert volt ampere to horsepower?

Converting volt ampere to horsepower helps compare electrical apparent power with mechanical power, which is important when equipment has both electrical inputs and mechanical outputs.

Does one volt ampere always equal one watt?

No, volt ampere equals watts only when the power factor is 1, meaning a purely resistive load; otherwise, apparent power and real power differ.
