WebNov 27, 2024 · For inductors in ac circuits, we find that when a sinusoidal voltage is applied to an inductor, the voltage leads the current by one-fourth of a cycle. The opposition of an inductor to a change in current is expressed as a type of ac reactance. This inductive reactance, which has units of ohms, varies with the frequency of the ac source. WebAs with inductors, the reactance equation’s 2πf term may be replaced by the lowercase Greek letter Omega (ω), which is referred to as the angular velocity of the AC circuit. Thus, the equation XC = 1/ (2πfC) could also be written as XC = 1/ (ωC), with ω cast in units of radians per second.
