Discussion
Two capacitors of very different values are connected in series across an alternating supply. Most of the voltage appears across
Answer: C
The same current, and therefore the same charge, passes through both, so the voltages divide inversely with the capacitances and the smaller one takes almost all of it. On a direct supply the long-term division would instead be settled by the ratio of the leakage resistances, which is a quite different calculation.
