The current in the given circuit is increasing with a rate `a=4 amp//s`. The charge on the capacitor at an instant when the current in the circuit is 2 amp will be:

In an L-C circuit, L = 0.75 H and C =18 muF , (a) At the instant when the current in the inductor is changing at a rate of 3.40 A /s , what is the charge on the capacitor? (b) When the charge on the capacitor is 4.2 xx 10^-4 C, what is the induced emf in the inductor?

After switch is closed in the LC circuit shown in the figure, the charge on the capacitor is sometimes zero, but at such instants the current in the circuit is not zero. How is this behaviour possible ?

In an L-C circuit, L = 0.75 H and C =18 muF , (a) At the instant when the current in the inductor is changing at a rate of 3.40 Ns , what is the charge on the capacitor? (b) When the charge on the capacitor is 4.2 xx 10^-4 C, what is the induced emf in the inductor?

The resistance in the following circuit is increase at a particle instant. At this instant the value of resistanc eis 10Omega . The current in the circuit will be now

The current through the capacitor in the given circuit is

The current through the capacitor in the given circuit is

In the circuit shown in the figure, the jockey J is being pulled towards right, so that the resistance in the circuit is increasing. It’s a value at some instant is 5Omega . The current in the circuit at this instant will be
