Question

In the circuit shown in the figure, find the maximum energy stored on the capacitor. Initially, the capacitor was uncharged.

• A. $150\mu C$
• B. $100\mu C$
• C. $50\mu C$
• D. Zero

Answer 1

The correct option is D Zero

This circuit consists of two closed loops. Let $i_1$ and $i_2$ be the current in these two loops.

It shows that no current is flowing in the branch containing $2\mu F$ capacitor.
It means that there will be no potential difference across the capacitor.

Now, we know that energy stored in the capacitor is given by
$U=\frac{1}{2}C{V}^2$
As $V=0$
$⟹U=0$
$\therefore$ The capacitor will not get charged at all.
