Definition of Charge and electron emission
Check what you remember
Read the wording for your board, then hide it and explain Charge and electron emission in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Emitted electrons are attracted back to a positive plate, so a positively charged electroscope does not discharge.
