The photocurrent in an experiment on photoelectric effect increases if

The collector plate in an experiment of photoelectric effect is kept vertical above the emitter plate. Light source is put on, and a saturation photocurrent is recorded. An electric field is switched on which has a vertically downward direction-

The anode plate in an experiment on photoelectric effect is kept vertically above the cathode plate. Light source is put on and a saturation photocurrent is recorded. An electric field is switched on which has vertically downward direction

Explain effect of potential on photoelectric current in experiment of photoelectric effect.

When stopping potential is applied in an experiment of photoelectric effect, no photocurrent is observed. This means that
