Define the term 'stopping potential' in relation to photoelectric effect.

Text Solution

Verified by Experts

Stopping potential is that minimum negative potential given to anode in a photocell for which the photoelectric current becomes zero. It is denoted by `Vs`. It is independent of the intensity of the incident light.
