2. Electric Potential and Capacitance
easy

Three identical capacitors are combined differently. For the same voltage to each combination, the one that stores the greatest energy is

A

Two in parallel and the third in series with it

B

Three in series

C

Three in parallel

D

Two in series and third in parallel with it

Solution

(c) $U = \frac{1}{2}C{V^2}$
Now if $V$ is constant, then $U$ is greatest when $'Ceq'$ is maximum. This is when all the three are in parallel.
