What does «potencia reactiva» mean in Spanish?
- Reactive power does not really have a character of being consumed; it only appears when there are coils or capacitors in the circuits. Such power has an average value of zero, so it does not produce the necessary work. It is said to be a derating power (which does not produce watts). Reactive power is measured in volt-amperes reactive (VAR) and is usually denoted by the letter Q.
