    The curve between current (i) and potential difference (V) for a photo cell will be

    A)                                  

    B)                          

    C)                                       

    D)

    Correct Answer: D

    Solution :

                       In photocell, at a particular negative potential (stopping potential V0) of anode, photoelectric current is zero, At the potential difference between cathode and anode increases current through the circuit increases but after some time constant current (saturation current) flows through the circuit even if potential difference still increasing.
