Vedclass · Answer

(D) The efficiency $\eta$ of a full-wave rectifier is given by the formula: $\eta = \frac{81.2}{1 + \frac{r_f}{R_L}} \%$. Here,$r_f$ is the forward resistance of the diode and $R_L$ is the load resistance. For an ideal diode,the forward resistance $r_f$ is negligible compared to the load resistance $R_L$ (i.e.,$r_f \ll R_L$). Therefore,the maximum efficiency is $\eta_{\max} = 81.2\%$.

The maximum efficiency of a full-wave rectifier is .........$\%$
