List of top Physics Questions on LCR Circuit asked in WBJEE

A capacitor of capacitance $'C'$, is connected across an ac source of voltage $V$, given by $V = V _{0} \sin \omega t$ The displacement current between the plates of the capacitor, would then be given by:

A series LCR circuit resonates at 10 kHZ. If the capacitor is 0.01 $\mu$F, the inductance used is approximately

An $L C R$ series circuit containing a resistance of $120 \,\Omega$ has angular resonance frequency $4 \times 10^{5} \,rad \,s ^{-1}$. At resonance the voltage across resistance and inductance are $60\, V$ and $40 \,V$ respectively. The values of $L$ and $C$ are

The electric potential at a point on the axis of an electric dipole depends upon the distance r (> > a) of the point from centre of the dipole as
