Rectifiers are used to convert
A
low voltage to high voltage
B
high voltage to low voltage
C
Alternating current to Direct current
D
Direct current to Alternating current
Explanation: 

Detailed explanation-1: -A half-wave rectifier uses one diode and converts half of the input alternating current to direct current and the full wave rectifier consists of two diodes in the two branches and converts the both positive-half cycle as well as negative-half cycle of the input alternating current to direct current.

Detailed explanation-2: -A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation (converting DC to AC) is performed by an inverter.

Detailed explanation-3: -A rectifier is a device that converts an oscillating two-directional alternating current (AC) into a single-directional direct current (DC).

Detailed explanation-4: -AC to DC conversion A full bridge rectifier can be used to convert AC to DC. In this device, 4 diodes are used which operates in forwarding bias and not in reverse bias. During the positive half cycle two of the diodes are operated and during the negative half cycle other two diodes and operated.

Detailed explanation-5: -These diodes take advantage of the p-n junction to convert AC to DC as a sort of electric “switch” that lets current flow in either the forward or reverse direction based on the p-n junction direction. Forward biased diodes let current continue to flow while reverse biased diodes block it.
