If the current passing through an inductor is increased by 20%, then the percentage increase in the energy stored in the inductor is
A coil of resistance $16 \Omega$ is placed with its plane perpendicular to a uniform magnetic field whose flux ($\phi$ in $10^{-3}$ weber) changes with time (t in second) as $\phi = 5t^2+4t+2$. The induced current at time $t=6$ seconds is
The inductance L, Capacitance C and resistance R are the values of the components connected in series to an ac source of angular frequency \(\omega\). The inductive and capacitive reactances are \(X_L\) and \(X_C\) respectively. If the circuit is purely resistive, then
If the rate of change of electric field across the plates of a parallel plate capacitor is E and the displacement current is I, then the area of one plate of the capacitor is (\(\epsilon_0\) is permittivity of free space)
