Quizplus · Accepted Answer

The peak voltage of a sinusoidal waveform is √2 times the RMS voltage.
Therefore, peak voltage = √2 × RMS voltage
In the case of the typical household AC voltage of 120 V, the RMS voltage is 120 V.
So, peak voltage = √2 × 120 V
= 169.7 V, which is closest to option B, 170 V.
