The peak voltage of Indian household AC at rms $230$ V is approximately:
A$230$ V, since the rms is always the peak in AC theory
B$325$ V, since $V_0 = V_{rms}\sqrt 2 = 230\sqrt 2$
C$163$ V, dividing the rms voltage by $\sqrt 2$
D$460$ V, equal to twice the rms reading on the wall
Answer & Solution
Correct answer: B. $325$ V, since $V_0 = V_{rms}\sqrt 2 = 230\sqrt 2$
$V_0 = V_{rms}\sqrt 2 = 230\sqrt 2 \approx 325$ V.
