A capacitor capacitance c1 is connected across the, Ask an Expert

Academics

A capacitor (capacitance C1) is connected across the terminals of an ac generator. Without changing the voltage or frequency of the generator, a second capacitor (capacitance C2) is added in series with the first one. As a result, the current delivered by the generator decreases by a factor of three. Assume that the second capacitor had been added in parallel with the first one, instead of in series. Find by what factor would the current delivered by the generator have increased?
