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