In an a.c. circuit, the rms voltage is $100\sqrt{2} V$. The peak value of voltage would be:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 200 V
The relationship between the $V_{rms}$ and Peak voltage $V_{peak}$ is,
$V_{rms}=\frac{V_{peak}}{\sqrt{2}}$
$V_{peak}=100\sqrt{2}×\sqrt{2}=200V$
