Output voltage, V across the load is
dc

Rectifier efficiency: It is calculated as the ratio of output power to input
power.

DC output power,

AC input power, P = Power dissipated in diode junction + Power

dissipated in the load =

The forward resistance, R of the diode is very small, and hence R can

be neglected in comparison with R .

This value of efficiency is considered low and ripple factor is considered

very high. A filter circuit has to be used to minimize the ripples.
Peak inverse voltage (PIV): As mentioned earlier, PIV is the maximum
