GCSE Combined Science · key term
The resistance of a single resistor that could replace a combination of resistors and draw the same total current at the same potential difference.
Used by AQA
Specification 6.2.2 · Paper 5, Paper 6
Revise: Series and Parallel CircuitsThe total is also the equivalent resistance: the resistance of one resistor that could replace the combination without changing the total current for the same supply potential difference.
When calculating equivalent resistance from measurements, use the potential difference across the whole resistor combination and the total current through it.
