Find the model graph attached.
Stopping potential is the negative potential when the photoelectric current in a circuit becomes nil or zero. It is also called as the cut-off potential.
The photoelectric current increases as there is an increase in the stopping potential, provided the frequency and the intensity of the incident light does not change. The current reaches its maximum when all the photoelectrons are collected or reach the collector plate. This is called as the Saturation point.
The photoelectric current becomes zero when none of the photoelectrons reaches the plate.

Stopping potential is the potential difference at which no more energetic electrons leaves the metal serve that is no more photoelectric emission occurs and thus no current flows at this potential.
Photoelectric current decreases with decreasing potential difference.
