Text Solution

Verified by Experts

Given, `V=220sqrt(2)sin(314t-phi)`
Comparing with general equation, we get
a) Peak voltage, `V_(0) = 220sqrt(2)`V
rms voltage, `V_(rms) = V_(0)/sqrt(2) = (200sqrt(2))/sqrt(2) = 200V`
b) Average voltage `barV = 2/piV_(0) = 2/pi xx 220sqrt(2) = (440sqrt(2))/pi`V
c) As, `omega = 314 rad s^(-1)`
`rArr = 2pif =314 rArr f= 50 Hz`
