Definition of Photocurrent and emission rate
Check what you remember
Read the wording for your board, then hide it and explain Photocurrent and emission rate in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Increasing intensity increases the number of photoelectrons emitted per second and hence the photocurrent.
