Vedclass · Answer

(C) In $AC$ circuits,a resistor dissipates energy in the form of heat due to the $I^2R$ loss,regardless of the phase difference. However,an ideal choke coil is an inductor with negligible resistance. In an ideal inductor,the phase difference between voltage and current is $90^{\circ}$,which makes the power factor $\cos(90^{\circ}) = 0$. Therefore,the average power consumed by an ideal choke coil is $P = V_{rms} I_{rms} \cos(90^{\circ}) = 0$. Thus,a choke coil controls the current in an $AC$ circuit without wasting electrical energy as heat.

In $AC$ circuits,a choke coil is preferred over resistors because:
