Question

The form factor of the sinusoidal waveform is?

(a) 1.11

(b) 2.22

(c) 3.33

(d) 4.44

I got this question during an interview for a job.

My query is from Voltage and Current Values of a Sine Wave topic in section Introduction to Alternating Currents and Voltages of Network Theory

Answer 1

Correct choice is (a) 1.11

The explanation is: Form factor of any waveform is defined as the ratio of the rms value to the average value of the wave. Form factor = Vrms/Vav = (Vp/√2)/0.637Vp=1.11.
