1.

The ratio of mean val ve onof AC isalf aycle to rms value(c)v12 : π

Answer»

option b) Average or mean value of a sinusoidal signal, Vav = 2*(Vpeak) / piand RMS value is Vrms = Vpeak / sqrt(2)therefore, Vav / Vrms = 2*sqrt(2) / pi

Well, the reciprocal of this ratio i.e., Vrms / Vav is called Form Factor and is approximately equal to 1.11 for sinusoidal signal.

Form factors can be useful in calculating RMS values for practical or design purposes when you know average value and vice versa.
