Question
What is cut-off or stopping potential?
✓
Answer
If increasingly negative potentials were applied to the collector in the experiment of the photoelectric effect, the photocurrent decreases and for some typical value $\left(-V_0\right)$, photocurrent becomes zero. This value of $V _0$ is termed as cut-off or stopping potential.
