INTERNAL RESISTANCE BOARD
Comparisons can be made between AA and D cells - internal resistance and maximum current.
It is hoped that students will see patterns - smaller resistors result in smaller terminal voltage and larger circuit currents.
Your ammeter should be connected between point X and the top of the resistor and your voltmeter across the resistor.
The voltage is measured across six low value 2.5 W resistorsSupplied with batteries.
