Question

Analyze the maximum value of voltage
An alternating voltage e = 200 sin 628t is applied to a device which offers an ohmic
resistance of 20 Q to the flow of current in the circuit. Then
OPTIONS
250 volt
150 volt
200 volt
180 volt​

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