Vedclass · Answer

(A) An inductor is a passive electronic component that stores energy in its magnetic field when electric current flows through it. The energy stored is given by $U = \frac{1}{2} L I^2$,where $L$ is the inductance and $I$ is the current. Thus,statement $(a)$ is correct.$A$ capacitor is a passive electronic component that stores energy in an electric field created by the potential difference between its plates. The energy stored is given by $U = \frac{1}{2} C V^2$,where $C$ is the capacitance and $V$ is the voltage. Thus,statement $(b)$ is correct.Statements $(c)$ and $(d)$ are incorrect because inductors do not store energy in electric fields (ideally) and capacitors do not store energy in magnetic fields.Therefore,both statements $(a)$ and $(b)$ are correct.
