AC Circuit Containing Pure Inductor L
In this lecture we learn the behavior of current with the AC applied voltage. Here an alternating voltage is applied across the inductor and an due to current flowing through the inductor an emf is induced in the conductor.
Inductor store the energy in the magnetic form. Therefore we can say inductor convert electrical to magnetic and magnetic to electrical energy.
In this circuit the current lags behind voltage by 90 degree as explained in the lecture.
