Description : List out advantages and disadvantages of bridge rectifier.

Answer : Advantages :  1. Bridge rectifier can be used in applications allowing floating output terminals i.e. not output terminal is grounded.  2. The need of center-tapped transformer is eliminated.  ... The value of the diodes used should be precise , else there will be an error in rectification
