For a time-dependent voltage v(t), which is periodic with period t, the rms voltage is defined to be
vrms = []. use this definition to determine vrms (in terms of the peak voltage v0) for
(a) a sinusoidal voltage, i. e, v(t) = v0sin(2πt/t) for ; and (b) a positive square-wave voltage, i. e, v(t) = v0,
