If the number of turns in the coil of a moving coil galvanometer decreases, the resistance of the galvanometer,

The current flowing through the inductor of self inductance 'L' is continuously increasing at constant rate. The variation of induced e.m.f. (e) versus $\dfrac{dI}{dt}$ is shown graphically by figure

Two coils P and Q have mutual inductance 'M' H. If the current in the coil P is $I = I_0 \sin \omega t$, then the maximum value of e.m.f. induced in coil Q is

In series LCR circuit C = 2 uF, L=1 mH and R= 10 $\Omega$. What is the ratio of energies stored in the capacitor and inductor when maximum current flows through circuit?
