Question

explain the effect of potential different on photo electric current
​

Answer 1

$\huge \red {answer}$

As the potential difference applied between plate P and collector C decreases the photoelectric current decreases. This shows that all photo-electrons are not emitted with the same kinetic energy and the maximum kinetic energy of the photoelectrons depends upon the frequency of incident light.

Answer 2

Answer:

As the potential difference applied between plate P and collector C decreases the photoelectric current decreases. This shows that all photo-electrons are not emitted with the same kinetic energy and the maximum kinetic energy of the photoelectrons depends upon the frequency of incident light.
