A full-wave p–n diode rectifier uses a load resistor of 1500Ω .  No filter is used.  The forward bias resistance of the diode is 10Ω . The efficiency of the rectifier is

a
81.2 %
b
40.6 %
c
80.66 %
d
40.2 %

detailed solution

Correct option is C

Efficiency η=0.812×RLRL+Rf×100                      =0.812×15001500+10×100                      =80.66%
