A bridge rectifier, is a group of rectifiers (4 in a single phase) wired so that each half of an AC current is passed to respective positive and negative lines of a DC output.
It provides full wave rectification of AC into DC.
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.

Either, it depends somewhat on application.

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.
how to make a bridge rectifier on breadboard
bridge rectifier is the best rectifier.
Merits a diode bridge rectifier is simple to build
application controlled rectifier
In bridge rectifier,two of the diodes are forward biased(i.e conducting current) at a time while in centre tapped rectifier 1diode is forward biased at a time.So,the flaw in bridge rectifier is that voltage loss is more in bridge rectifier than in centre tapped rectifier. e.g:for silicon diode loss=-0.7v (for centre tapp) loss=2*0.7=1.4v (for bridge)
Bridge Rectifier
A bridge rectifier refers to a diode bridge of 4 diodes in a bridge configuration that provides some polarity of the output for either the polarity of the input or output.
