how do you define rectifier? please simplify it for me.?

Answer 1

hi there..

first of all the term rectifier itself suggests that it rectifies.. which means like to purify.
as we use the AC (Alternate Current).. it is having a shape with up and down ripples..

Function of Rectfier:
It converts AC into pulsating DC. As the DC is not continuous.. to make it continuous.. after that we have to use another circuits like filter and for precise voltage and current. we use regulator..

Answer 2

A rectifier is a device that passes a flow (usually referring to an electric current) through in one direction but not the other. A silicon diode is an example; it consists of a layer of n-type silicon adjoining a p-layer; in one direction, electrons in the n-layer are pushed toward the p-layer by the applied external voltage; the electrons combine with the holes in the p-layer and current flows. If the voltage is reversed, the electrons are drawn away from the p-layer, and the holes away from the n-layer, so no current flows.

Answer 3

A rectifier is an electrical device, which converts alternating current to direct current, a process known as rectification. Rectifiers are used as components of power supplies and as detectors of radio signals. Rectifiers may be made of solid state diodes, vacuum tube diodes, mercury arc valves, and other technologies
