The peak value of e.m.f. generated by an AC generator depends upon:

If frequency of an AC generator is doubled, the maximum value of emf induced in its coil will:

Two identical bulbs are connected to an AC source by using an inductor and a capacitor in series with the bulbs as shown in the figure. The brightness of the bulbs $B_1$ and $B_2$ will be

At a certain moment, the switch shown in the figure is disconnected. The energy of the oscillations immediately after the switch $S$ is disconnected and at time $0.1 \sec$ from the time switch is disconnected are, respectively
