What Real meters means in Physics A-Level, as defined for AQA.
Definition of Real meters
Check what you remember
Read the wording for your board, then hide it and explain Real meters in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Have small but non-zero ammeter resistance and large but finite voltmeter resistance, which cause small measurement errors.
