    Question

    The device which converts AC to DC is

    A Oscillator Correct Answer Incorrect Answer
    B Amplifier Correct Answer Incorrect Answer
    C Rectifier Correct Answer Incorrect Answer
    D None of these Correct Answer Incorrect Answer

    Solution

    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 process is known as rectification. Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves9 solidstate diodes, silicon-controlled rectifiers and other silicon -based semiconductor switches, Rectifiers have many uses, but are oftenfoundservingascomponentsofDCpower supplies and high-voltage direct current power transmission systems.
