Homework Help: The half-wave rectification of an alternating current

  1. Dec 1, 2013 #1
    1. The problem statement, all variables and given/known data

    Explain the use of a single diode for the half-wave rectification of an alternating current.

    3. The attempt at a solution

    A rectifier is a device that converts an alternating current, which periodically changes polarity, to direct current, which flows in only one direction. The half wave rectifier allows only one half of the alternating current to pass while the other half is blocked. This is achieved by using only a single diode.

    I'm not sure that it is right answer.

    You've described what a rectifier and half-wave rectifier does, and then you asserted this functionality can be achieved with a single diode. I don't see any explanation there.
