Pure Inductive AC Circuit ::
In the case of alternating current, as the electric current flows, it sets up a magnetic effect. This magnetism alters the electromotive force. The primary role of the inductor is to reduce the fluctuation during the flow of high currents and voltage.
In the AC Circuit containing inductance only, as the applied voltage varies and reverses polarity, the inductor stores energy continuously only as magnetic energy without preventing the flow of the electric current.
Inductance also prevents voltage fluctuation. The alternating current’s opposition caused by inductance is called reactance. In the AC Circuit containing inductance only, there will be no effect of resistance and capacitance in the circuit. Hence, it will lag the voltage by an angle of 90°.
