Specified practical work — Specified practical work – Determination of the internal resistance of a cell
The specification requires determination of a cell's internal resistance from current and terminal-potential-difference measurements.
Interactive Practical · A-Level Physics
EMF and internal resistance
Vary the external load, measure terminal potential difference and current, then determine emf and internal resistance from a straight-line graph.
This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
