The current flowing through an inductor of self inductance L is continuously increasing. Plot a graph showing the variation magnetic potential energy stored versus the current.

When a circuit element X is conneted across a.c. sourceof emf 220sqrt2V , a current sqrt2 A flows through it and this current is in phase with applied voltage. When another element Y is connected across same a.c. source, the same current flows in the circuit, but it leads the voltages by pi//2. Plot a graph showing variation of net impedance of series combination of X and Y as a function of angular frequency of applied voltage.

In an inductor of self inductance L = 2 mH, current changes, with time according to relation I = t^2 e^-t . At what time, e.m.f. is zero?

A circular coil 'A' has a radius R and the current flowing through it is I. Another circular coil 'B' has a radius 2R and if 2I is the current flowing through it, then the magnetic fields at the centre of the circular coil are in the ratio of
