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 = 1.57Read more on Sarthaks.com - https://www.sarthaks.com/492695/alternating-voltage-200-sin-314t-is-applied-to-device-which-offers-ohmic-resistance-of-20
