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. WebDec 10, 2016 · In this type of circuit, the current lags behind the voltage by an angle of 90 degrees. So, the phase angle between v (t) and i (t) in the given circuit is 90°. Phasor Diagram: The clockwise direction is taken as the positive direction. ∴ We can conclude that the current (I) lags the voltage (V) in a purely inductive circuit. Important Points:

WebWe see that the current lags in phase 90 behind the emf. The reason is that, if you suddenly apply an external voltage, the current takes a while to build up, because the induced magnetic eld opposes the buildup according to Lenz’s law. So, in an inductor the voltage leads the current. In the complex notation, this means that, if Ee(t) = E 0e ...
