    In a forward biased region of a pn junction diode
    Question

    In a forward biased region of a pn junction diode

    A.

    the diode current increases exponentially with decrease in voltage

    B.

    the diode current decreases exponentially with increase in voltage

    C.

    the diode current increases exponentially with increase in voltage

    D.

    the diode current decreases exponentially with decrease in voltage

    Correct option is C

    In a forward-biased pn junction diode, the voltage applied across the diode reduces the barrier potential, allowing charge carriers (electrons and holes) to cross the junction more easily. As a result, the current through the diode increases exponentially with the increase in the applied forward voltage.
