Practicing Success
In an experiment on photoelectric effect, with the increase in potential difference of emitter and collector plate, keeping the frequency and intensity of the incident light fixed, what happens to the photocurrent ? |
increases decreases remains constant increases initially and then becomes constant |
increases initially and then becomes constant |
As the potential difference increases, the photocurrent increases as more and more electrons are repelled from the cathode and attracted to the anode. This continues for a while after which it becomes constant. |
