The average value for half cycle in a 200 V AC source isA. 180 VB. 200

1.	The average value for half cycle in a 200 V AC source isA. 180 VB. 200 VC. 220 VD. none
Answer» (a) `V_(rms) = (V_(0))/(sqrt(2))` therefore `V_(0) = sqrt2 V_(rms)` therefore `V_(av) = (2V_(0))/ (pi) = (2)/(pi) sqrt 2V_(rms) = (2sqrt2 xx 200)/(pi) = 180 V`
