Physics Question on Photoelectric Effect
The incorrect statement for saturation current in a photoelectric cell is
A
All the electrons emitted from the photosensitive plate reach the collector.
B
The potential difference between the emitter and collector should be equal to the stopping potential
C
Collector is +VE w.r.t emitter
D
It is the maximum current that can be set up in the photoelectric cell.
Answer
The potential difference between the emitter and collector should be equal to the stopping potential
Explanation
Solution
For saturation current emitter is +ve and for cut off potential the emitter is -ve.
