In photoelectric effect, keeping the frequency of incident radiation and accelerating potential fixed, if the intensity of incident light is increased, (a) the photoelectric current increases. (b) the kinetic energy of emitted photoelectrons increases. (c) photoelectric current decreases. (d) kinetic energy of emitted photoelectrons decreases.

Answer: (a). Higher intensity means more photons per second, so more photoelectrons per second. Maximum KE depends only on frequency, which is fixed. So the answer is (a) the photoelectric current increases.
