(i) Saturation current is same for incident radiations of different frequencies but of same intensity. It does not change with increase in anode potential.

(ii) Stopping potential is same for incident radiation of different intensities but same frequency. This is because stopping potential depends on frequency and not on the intensity of incident radiation.

(iii) Photoelectric current increases linearly with the intensity of incident radiation of same frequency.
