Vedclass · Answer

(A) The energy stored in a capacitor is given by $U = \frac{1}{2} C_{eq} V^2$,where $C_{eq}$ is the equivalent capacitance and $V$ is the potential difference across the combination.Since the potential difference $V$ is constant,the stored energy $U$ is directly proportional to the equivalent capacitance $C_{eq}$ $(U \propto C_{eq})$.To maximize the stored energy,we must maximize the equivalent capacitance $C_{eq}$.For a given set of capacitors,the equivalent capacitance is maximum when they are connected in parallel $(C_{eq} = C_1 + C_2 + C_3)$.Therefore,all capacitors should be connected in parallel to maximize the stored energy.

If there are three capacitors and a source with $e.m.f. \ V$,how should the three capacitors be connected to the source to maximize the stored energy?
