Plot a graph showing the variation of induced e.m.f. with the rate of change of current flowing through a coil.
OR
A series combination of inductor (L), capacitor (C) and a resistor (R) is connected across an ac source of emf of peak value E₀ and angular frequency (ω). Plot a graph to show the variation of impedance of the circuit with angular frequency (ω).
