(D) In a photocell,when the potential difference $(V)$ between the cathode and anode is varied,the photoelectric current $(i)$ changes.At a specific negative potential of the anode relative to the cathode,known as the stopping potential $(V_0)$,the photoelectric current becomes zero because even the most energetic photoelectrons are repelled.As the potential difference $(V)$ increases from this negative value towards positive values,the photoelectric current $(i)$ increases.Eventually,for a given intensity of incident radiation,the current reaches a maximum value called the saturation current,beyond which it remains constant even if the potential difference is further increased.

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