Answer:
Rectifier efficiency is defined as the ratio of DC power to the applied input AC power. The AC input power is given by: P ac= I 2 rms(r f + R L) , where r f is diode resistance. Therefore, maximum rectifier efficiency = 40.6%. This means only 40.6% of the input AC power is converted into DC power.
