Does saturation photocurrent depend on frequency?
The saturation current depends on the intensity of light, not on frequency. Hence no matter how much is the frequency for the same intensity of light, the saturation photocurrent will be same.
What is the effect of frequency on saturation current?
If you increase the frequency of the photon, you increase the electron’s kinetic energy outside the surface. When the increase you increase the frequency you increase stopping potential but the saturation current remains the same for a given intensity.
Does saturation current depend on intensity?
The value of saturation current depends on intensity. It is independent of stopping potential.
Why is saturation current same for different frequencies?
The saturation current depends on number of electrons passing through the given area in unit time. Since the number of saturation electrons does not depends on frequency hence the saturation current does not depends on frequency.
What happens to the photocurrent when you increase the potential V will it saturate?
when accelerating potential is increased,the photocurrent increases upto a certain level after which it saturates as all the emitted electrons are collected by the collector plate. but when intensity is increased,the current is directly proportional and does not saturate.
Are intensity and current the same?
Definition: The electrical current is a physical phenomenon caused by the displacement of electrons or ions that induce electric fields. By convention, current is considered to be a flux of positive charges. The intensity of the current is the quantity of charge which passes in a conductor per unit of time.
What is the relationship between intensity of light and current produced?
the number of electrons (i.e. the electric current) is proportional to the light intensity (at a fixed wavelength) and independent of the frequency of the incident radiation above the threshold value of ν0 (no current is observed below ν0).
What is current intensity in electricity?
: the magnitude of an electric current as measured by the quantity of electricity crossing a specified area of equipotential surface per unit time.
