In an ac circuit the current lags behind
WebFeb 19, 2024 · The phase difference is <= 90 degrees. It is customary to use the angle by which the voltage leads the current. This leads to a positive phase for inductive circuits … WebMay 1, 2024 · 5 Answers Sorted by: 2 Because inductors are made to react against the change in current, it causes it to lag behind the voltage. When you apply a voltage to an inductor, you make a magnetic field. Henceforth, if the magnetic field varies with respect to time, there is an electric field that opposes the magnetic field inside the inductor.
