RECTIFIER

Rectifier is an electronic device that converts alternating current into direct current is called rectifier.
A rectifier changes A.C into D.C by eliminating the negative half cycles of the alternating voltage.  It may work as a switch that closes a load circuit during the positive half cycle of A.C supply and opens the circuit during the negative half cycle.  Therefore a rectifier provides one-way path for electric current.
