Q. An alternating voltage of $141.4V\ (rms)$ is applied to a vacuum diode as shown in the figure. The maximum potential difference across the condenser will be
A) 100 $V$
B) 200 $V$
C) 100$\sqrt{2}\ V$
D) 200$\sqrt{2}V$
Explanation
(b) $V_{peak} = \sqrt{2}\ V_{rms} = \sqrt{2} \times 141.4 = 200\ V$
