Ideal op-amp assumptions
What Ideal op-amp assumptions means in Physics A-Level, as defined for AQA.
Definition of Ideal op-amp assumptions
Check what you remember
Read the wording for your board, then hide it and explain Ideal op-amp assumptions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The open-loop gain is infinite and the input resistance is also infinite, so no current flows into either input.
