According to photoelectric effect, speed of
electron (kinetic energy) emitted depends
upon frequency of incident light while
number of photoelectrons emitted depends
upon intensity of incident light. Hence, as
the intensity of light increases, the
photocurrent increases. In a photo-cell, the
photocurrent has no relation with the applied
voltage.
Stopping potential is the (negative) potential
at which the current is just reduced to zero.
It is independent of intensity of light but
depends on the frequency of light similar to
K.E.

Photocurrent increases with intensity of light
Photocurrent is the flow of electric current in a photocell or photodiode when it is exposed to light. It is a measure of the number of electrons that are released from the material in response to the incident light. The intensity of light refers to the amount of light energy per unit area falling on a surface.
When light falls on a photocell, the photons of light energy are absorbed by the material in the photocell. This absorption of energy causes the electrons in the material to gain enough energy to break free from their atomic bonds and become free electrons. These free electrons are then available to flow as an electric current.
Explanation:
When the intensity of light incident on the photocell increases, the number of photons hitting the surface of the photocell also increases. This means that there are more photons available to be absorbed by the material in the photocell. As a result, more electrons are freed from their atomic bonds, leading to an increase in the number of free electrons available to flow as photocurrent.
The relationship between the intensity of light and the photocurrent is directly proportional. This means that as the intensity of light increases, the photocurrent also increases. Conversely, when the intensity of light decreases, the photocurrent decreases.
This relationship can be explained by considering that the energy of a photon is directly proportional to its frequency (E = hf), where h is Planck's constant and f is the frequency of the light. Therefore, higher intensity light corresponds to a higher number of photons with higher frequencies. This higher energy light provides more energy to the electrons in the material, allowing them to overcome the binding forces and become free electrons.
In conclusion, the correct statement is option A - Photocurrent increases with intensity of light.
