Vedclass · Answer

(B) choke coil is an inductor used to control the current in an $AC$ circuit without significant power loss. The power dissipated in an $AC$ circuit is given by $P = V_{rms} I_{rms} \cos \phi$,where $\cos \phi = \frac{R}{Z}$ is the power factor. For an ideal choke coil,the resistance $R$ should be as small as possible compared to the inductive reactance $X_L$. Therefore,for an efficient choke coil,$X_L >> R$.

In a choke coil,the reactance $X_L$ and resistance $R$ are such that
