Question

an alternating voltage is expressed by equation e= 200sin314t . Determine 1 average value .2 form factor​

Answer 1

Answer:

Comparing the given voltage equation with the standard form of alternating voltage equation we find that Vm = 200 V R = 20 Ω Im = 200/20 = 10 A.For such a half-wave rectified current RMS value = Im/2 = 10/2 = 5A. Average current = Im/π = 10/π = 3.18 A ; Form factor = 5/3.18 = 1.57
