Internal Resistance Board

Back    

Internal Resistance, A1-1065.00, £30.40

Internal Resistance BoardThe voltage is measured across six low value
2.5 W resistors.

Comparison can be made between the 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.

Although this board was designed to be used with the ALBA Interface and Logger it can be used without a computer. Your ammeter should be connected between point X and the top of the resistor and your voltmeter across the resistor.

Supplied with batteries.
