A p-n diode is used in a half wave rectifier with a load resistance of `1000 Omega `. If the forward resistance (`r_f`) of diode is `10 Omega `, calculate the efficiency of this half wave rectifier.

Text Solution

Verified by Experts

Load resistance `R_(L)= 1000Omega,`
Forward resistance of the diode` =r_(f) = 10Omega`
Efficiency of half wave rectifier
`[(0.406R_(L))/(r_(f)+R_(L))]=(0.406xx1000)/(1010)=0.4019.`
The percentage efficiency of the half wave rectifier `eta=40.19%`
