What determines the strength of photoelectric current?

What is photoelectric effect?

State the influence of work function on kinetic energy of electrons emitted in a photocell. If the intensity of the incident radiation is doubled, what changes occur in the stopping potential and photoelectric current?

State the dependence of work function on kinetic energy of electrons emitted in a photocell. If the intensity of the incident radiation is doubled, what changes occur in the stopping potential and photoelectric current?

Draw a plot showing the variation of photoelectric current versus the intensity of incident radiation on a given photosensitive surface.

In an experiment on photoelectric effect, the following graphs were obtained between the photoelectric current 'I' and anode potential V. Name the characterstics of this incident radiation that was kept constant in this experiment.

What is the strength of the electric field inside a charged spherical shell?
