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

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.

A full wave rectifier uses two diodes with a load resistance of 100 Omega . Each diode is having negligible forward resistance. Find the efficiency of this wave rectifier.
