Definition of Current balance

Check what you remember

Read the wording for your board, then hide it and explain Current balance in your own words. Rough notes are fine. This is a self-check, with no mark or grade.

Reference: AQA

Because negligible current enters the ideal op-amp input, the sum of the input currents equals the current through the feedback resistor.
