Stopping potential is defined as the minimum negative potential gradient of the plates at which the photoelectric current becomes zero. In case of stopping potential, the value of retarding potential difference between two plates is sufficient to stop the most energetic photoelectrons emitted. It is not dependent on the intensity of incident light.

– Physics What is cut-off or stopping potential? If increasingly negative potentials were applied to the collector in the experiment of the photoelectric effect, the photocurrent decreases and for some typical value (– V 0 ), photocurrent becomes zero. This value of V 0 is termed as cut-off or stopping potential.

Stopping potential or cutoff potential is defined as the required potential for stopping the removal of an electron from a metal surface when the incident light energy is greater than the work potential of the metal on which the incident light is focused. Stopping potential does not depend on the intensity of incident radiation.
