what is the difference between the diode and the rectifier

Answer Posted / avinash kumar

A diode is a device which allows the current to flow in one direction only, it is a thermionic tube have two electrodes acts as a rectifier (conversion of ac to dc), these days semiconductor diode is most common type having a p-n junction
while
A rectifier is a device which is used to convert the ac voltages to dc voltages, actually it rectify the sinusoidal voltages to unidirectional voltages and it allow the currents to flow in both the directions.
