    As the intensity of incident light increases

    A) Photoelectric current increases

    B) Photoelectric current decreases

    C) Kinetic energy of emitted photoelectrons increases

    D) Kinetic energy of emitted photoelectrons decreases

    Correct Answer: A

    Solution :

    [a] Intensity increases means more photons of same energy will emit more electrons of same energy, hence only photoelectric current increases.
