Q1:

The maximum rectification efficiency in case of full wave rectifier is

A 100%

B 81.2%

C 66.6%

D 40.6%

ANS:B - 81.2%

A Full Wave Rectifier is a circuit, which converts an ac voltage into a pulsating dc voltage using both half cycles of the applied ac voltage.

The maximum efficiency for a half wave rectifier is 40.6% and for full wave rectifier it is 81.2%.

Maximum efficiency=dc output power/ac input power.
