Current in the photoelectric effect is directly proportional to the intensity of the incident light. So,to increase current we have to increase intensity of the light. Current is independent of frequency and wavelength of the incident light.

The photoelectric current can be increased by
In a photoelectric experiment, if the intensity of incident light increases, the saturation current increases.
The photo current in an experiment on photoelectric effect increases if
(a) the intensity of the source is increased
(b) the exposure time is increased
(c) the intensity of the source is decreased
(d) the exposure time is decreased
What is photoelectric effect? Explain the effect of increase (i) frequency (ii) intensity of incident radiation on photoelectric current with suitable graphs.
Light of particular frequency v is incident on a metal surface. When the intensity of incident radiation is increased, the photoelectric current
