The graph between photo electric current and cathode potential when the anode is kept at zero potential, for light of two different intensities out of the same frequency looks like the one:

In the following figure the curves have been drawn between the photoelectric current and the potential difference applied at the cathode with respect to anode at four different intensities, the stopping potential is represent by

Plot a graph showing the variation of photoelectric current with anode potential for two light beam of same wavelength but different intensity.

if the cathode and the anode are kept at the same potential, the emitted electrons have

if the cathode and the anode are kept at the same potential, the emitted electrons have

In a plot of photoelectric current versus anode potential, how does (i) the saturation current vary with anode potential for incident radiations of different frequencies but same intensity? (ii) the stopping potential vary for incident radiations of different intensities but the same frequency? (iii) Photoelectric current vary of different intensities but same frequency of incident radiation? justify your answer is each case.
