A: This type of rectifier circuit will conduct current trough a load both times during the AC positive and negative cycle
The output degrades to a half-wave rectifier.
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
The a.c. component, or ripple, produced by the 4-diode (full wave) bridge rectifier is the same as that produced by the 2-diode full wave rectifier. The bridge is connected across the secondary winding of a transformer. The 2 diodes of the other type of full wave rectifier are each connected to one end of a winding, but that winding requires a center tap. For any desired value of d.c. after rectification, the a.c. voltage of the 2-diode rectifier winding has to be twice that of the winding required for the bridge.
Since the output of the rectifier is a close approximation of a sawtooth waveform, then all harmonics starting at the second harmonic are present in the full wave bridge rectifier output.
A full-wave bridge rectifier with 4 diodes gives a dc output voltage equal to the average voltage of the whole transformer secondary. A FW rectifier with 2 diodes and a centre-tapped secondary gives an output voltage equal to the average voltage of half the secondary. If you have a 12-0-12 transformer, the bridge gives a 24 v output, while the 2-diode FW rectifier gives 12 v (approximately).
Bridge Rectifier DiodesIn a "bridge" rectifier there is 4 diodes In a "full wave" there are 2 diodes.In a "half wave" rectifier there is 1 diode.
The output degrades to a half-wave rectifier.
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
They both have the same current.
rectifier is used to resist the current likewise in bridge wave rectifier ,the inductive load is used to resist high amount of current because in bridge wave we cannot resist the current by using rectifier ..so we are using inductive load here
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
Use a full wave bridge rectifier.
Efficiency is double in case of full wave rectifier.

a full-wave bridge rectifier
There are basically two types of rectifiers one is the half wave rectifier and the other is the full wave rectifies. The full wave rectifier is further classified into two types namely the bridge rectifier and the center tapped rectifier.There are also silicon controlled rectifiers nowadays.
