In photoelectric experiment keeping the frequency of incident radiation and accelerating potential fixed, if the intensity of incident light is increase,
  1. photoelectric current decreases
  2. kinetic energy of emitted photoelectron decreases
  3. photoelectric current increases
  4. kinetic energy of emitted photoelectrons increases

Solution

Photoelectric current is proportional to the intensity of the incident light.
