Combination of Capacitors

Two capacitors $C_1$ and $C_2$ are connected in parallel to a battery. Charge-time graph is shown below for the two capacitors. The energy stored with them are $U_1$ and $U_2$ , respectively. Which of the given statements is true?

Show answer and solution

Answer: (a)

In parallel both have the same final voltage $V$ , and final charge $q = CV$ .
From the graph, $C_2$ reaches a higher final charge, so $C_2 > C_1$ .
$U = \frac{1}{2}qV$ with the same $V$ , so $U_2 > U_1$ .
So the answer is (a) $C_2 > C_1, U_2 > U_1$ .
