Name the device which converts an ac input signal into a dc output signal. Write three advantages of the device.
 

A rectifier is a device that transforms alternating current (AC) in two directions that is oscillating into.
direct current in only one direction (DC).

1. Rectifiers come in many different physical configurations, ranging from vacuum tube diodes,
   crystal radio receivers, and contemporary silicon-based diodes.
2. Rectifier has the ability to transform an alternating current into a unidirectional or pulsed.
   form of direct current.
3. They are used as components of DC power supplies and high-voltage direct-current power transmission systems.
