Question:

In an a.c. circuit, the rms voltage is $100\sqrt{2} V$. The peak value of voltage would be:

Options:

200 V

100 V

141 V

70.5 V

Correct Answer:

200 V

Explanation:

The correct answer is Option (1) → 200 V

The relationship between the $V_{rms}$ and Peak voltage $V_{peak}$ is,

$V_{rms}=\frac{V_{peak}}{\sqrt{2}}$

$V_{peak}=100\sqrt{2}×\sqrt{2}=200V$
