Lost Volts Apparatus

Simple to use | No confusion | Reliable data

This 'Lost Volts' apparatus provides a convenient solution for experimentally determining the internal resistance and the EMF of a cell.

The unit houses seven appropriately rated resistors and a push switch and is designed to remove any complications from wiring separate resistors. The switch reduces the possibility of unnecessary drain of the battery and excessive heat being generated in the resistors.

Lost Volts Separates

Good circuit construction exercise | Full instructions | Reliable data

A pack of 5 convenient and appropriately rated mounted components to enable students to carry out an experiment to determine the EMF and internal resistance of a cell.

The pack is supplied with full instructions and the resistors can be combined to create up to nine different resistances allowing a good range of readings to be taken.

The unit houses seven appropriately rated resistors and a push switch and is designed to remove any complications from wiring separate resistors. The switch reduces the possibility of unnecessary drain of the battery and excessive heat being generated in the resistors.
