In a full wave rectifier output is taken across a load resistor of `800 ohm`. If the resistance of diode in forward biased condition is `200 ohm`, the efficiency of rectification of `ac` power into `dc` power is.

A

`64.96%`

B

`40.6 %`

C

`81.2 %`

D

`80%`

Text Solution

Verified by Experts

The correct Answer is:
A
`eta=0.812xx(R_(l))/(R_(l)+r_(f))=(0.812xx800)/(800+200)`
`=64.96%`
