Light of intensity I and frequency nu is...

Light of intensity I and frequency `nu` is incident on a photosensitive surface and causes photoelectric emission. What will be the effect on anode current when (i) the intensity of light is gradually increased, (ii) the frequency of incident radiation is increased and (iii) the anode potential is increased? In each case, all other factors remains the same. Explain, giving justification in each case.
