A bridge recifier is a full wave rectifier. It takes each part of the AC waveform, rectifies it and adds them together, giving a smoother output compared to a half wave recifier.
They are used in simple power supplies, using a mains transformer, a bridge rectifier and a smoothing capacitor.
Further regulation can then be added for stable power supplies.
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.

give answer how to control the speed of dc motor using bridge rectifier ? ANSWER: A bridge rectifier by itself does not control anything it merely convert AC into DC. the controlling is done by other means SCR TRIACS AND SERVO loop
you only use half the number of windings in the bridge comparing it to the center tapped , and in the bridge rectifier the peak inverse voltage that a diode must be able to sustain without break down is half of that in the center tapped PIV per diode: center tapped: 2Vm : bridge : 1Vm
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
Merits a diode bridge rectifier is simple to build
there is no need of bulky centre tap in a bridge rectifier. TUF(transformer utilisation factor) is considerably high. output is not grounded. diodes of a bridge rectifier are readily available in market. *the PIV(peak inverse voltage) for diodes in a bridge rectifier are only halfof that for a centre tapped full wave rectifier,which is of great advantage.
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.
bridge rectifier is the best rectifier.
how to make a bridge rectifier on breadboard
Total cost to make a bridge rectifier is about Σ25. A bridge rectifier is an electrical device that converts alternating currents (AC) to direct current (DC). The process of bridge rectification is a simple one using four diodes, two AC and two DC wires, an AC source and pliers.
What are applications of rectifiers
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
Bridge Rectifier
It's the only way to accomplish full-wave rectification of AC without a center-tapped transformer winding.
What is the advantage of using the bridge rectifier A: NONE no advantage the only advantage can be considered it the fact it will provide more voltage but never more power actually less by a .7 volt diode drop
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.
