The maximum photoelectric current at high positive voltage is the:
ASaturation current
BAlternating current
CDisplacement current
DPhotoelectric wave
Answer & Solution
Correct answer: A. Saturation current
1. Raising the collector voltage gathers more electrons.
2. Eventually every emitted electron is collected.
3. The current then levels off at the saturation current.
4. So the answer is saturation current.
