If the incident radiation of same frequency but different intensity $I_1 , I_2 \text{ and } I_3$ falls on the plates , variation of photo electric current with collector plate potential is shown in figure with different intensities.

Which is correct?

$I_3> I_2 >I_1$

$\text{At a given frequency the photoelectric current is proportional to the Intensity}$

$\Rightarrow I_3> I_2 >I_1$
