An oscillator circuit consists of an inductance of $0.5 \ mH$ and a capacitor of $20 \ \mu F$. The resonant frequency of the circuit is nearly......$Hz$

Which physical quantity is there in $A.C.$ circuit as displacement variable?

$A$ fully charged capacitor $C$ with initial charge $q_0$ is connected to a coil of self-inductance $L$ at $t = 0$. The time at which the energy is stored equally between the electric and the magnetic fields is:

In the given $L-C$ circuit,inductance is $80 \mu H$ and capacitance is $20 \mu F$. The maximum potential difference across the capacitor is $80 \ V$. The maximum current is (in $A$)

$A$ capacitor of capacity '$C$' is charged to a potential difference of '$V_1$'. The plates of the capacitor are then connected to an ideal inductor of inductance '$L$'. The current through the inductor when the potential difference across the capacitor reduces to '$V_2$' is:

An $LC$ resonant circuit contains a $400 \, pF$ capacitor and a $100 \, \mu H$ inductor. It is set into oscillation coupled to an antenna. The wavelength of the radiated electromagnetic waves is
