Definition of Photoelectric current
Check what you remember
Read the wording for your board, then hide it and explain Photoelectric current in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A current proportional to the rate of emission of photoelectrons, so proportional to intensity at constant frequency above threshold.
