WebReactive power is a type of power that does no real work and is generally associated with reactive elements (inductors and capacitors). For example, the inductance of a load such as a motor causes the load current to lag behind the voltage. Power appearing across the inductance sloshes back and forth between the inductance itself and the power ... WebApr 9, 2024 · What is Reactance? The measure of the opposition of inductance and capacitance to current in an AC circuit is known as reactance, denoted by X. It varies with the frequency of electrical signals and is measured in ohms. Reactance is of two types: Capacitive reactance ( X C ), and Inductive reactance ( X L ). Reactance Formula
