Efficiency of a bridge rectifier is approximately …………… .

Efficiency of half wave rectifier is approximately

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.

In a half wave rectifier, a p-n junction diode with internal resistance 20 ohm is used. If the load resistance of 2 ohm is used in the circuit, then find the efficiency of this half wave rectifier.
