Two capacitorsc1 30 microf andc2 30 microfare connected, Ask an Expert

Academics

Two capacitors,C1 = 30 µF andC2 = 3.0 µF,are connected in parallel and charged with a 100 V power supply.

(a) Calculate the total energy stored in twocapacitors.

(b) What potential difference would be required across the same twocapacitors connected in series in order that the combination storethe same energy as in (a)?
