If the maximum load voltage of 40 V is to be obtained from the bridge rectifier, the value of rms from the secondary is approximately ………

A

0 V

B

14.4 V

C

28.3 V

D

56.6 V

Text Solution

Verified by Experts

The correct Answer is:
C
28.3 V
rms voltage of output
`(V_(0))_("rms")=(V_(m))/(sqrt(2))`
`=(40)/(sqrt(2))=28.8V ~~28.3V`
