Question

A photocell employs photoelectric effect to convert :- (A) change in the frequency of light into a change in the electric current (B) change in the frequency of light into a change in electric voltage (C) change in the intensity of illumination into a change in photoelectric current (D) change in the intensity of illumination into a change in the work function of the photocathode.

The photoelectric current is directly proportional to the intensity of illumination. Therefore a change in the intensity of the incident radiation will change the photocurrent also.
