Question

Quizplus · Accepted Answer

The typical household electricity in the United States and Canada is supplied at 120 V RMS (root mean square), which corresponds to an amplitude of approximately 170 V. This is because the RMS value of a sinusoidal voltage, like that supplied to households, is its peak (or amplitude) value divided by the square root of 2.
