Question
The curve between current $(i)$ and potential difference $(V)$ for a photo cell will be
✓
Answer
(d) In photocell, at a particular negative potential (stopping potential $V_0$) 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.
