A single diode can transmute AC power into an intermittent DC flow, but a bridge rectifier uses 4 diodes to reverse the direction of each side of the AC pulse. With a bridge rectifier, the DC still fluctuate from 0 to a peak value, but it does not cut out half the time.
Question : Rectifiers are used to convert:
Option 1: High voltage to low voltage
Option 2: Low voltage to high voltage
Option 3: Direct Current (DC) to Alternating Current (AC)
Option 4: Alternating Current (AC) to Direct Current (DC)
