IB PHYSICS > PRACTICAL WORK > IB IA EXPERIMENTS - always a good idea to look at this before submitting your work. =PRACTICAL: INTERNAL RESISTANCE OF A CELL= Construct a circuit of a cell and variable resistor (0-15 Ω is ideal). Connect voltmeters and ammeters to measure the PD across the cell and the current through it. Take at least five readings over as large a range as possible. Remember to note down uncertainties, Plot a graph of V against I and use it to calculate the EMF and internal resistance of the cell (with uncertainties).
