An electric generator produces electricity by an alternating current with a frequency of 50 cycles per second. If the rms voltage is 100 V, what is the approximate maximum potential difference produced by the generator?

Correct Answer: C. 141 V.
By definition, Vrms = Vmax / sqrt(2). Therefore, Vmax = sqrt(2)*Vrms = (1.41)(100V) = 141 V.
