    Uses of diodes

    Sajin John asks:

    “What is the job of diode in a circuit? How can we recognize it?”


    A diode is a two terminal electronic device which allows passage of current only in one direction.

    A diode is used for rectification (converting ac to dc) and many other circuites

    See the image of a diode on the left.
