Lost volts

Lost Volts Apparatus

This 'Lost Volts' apparatus provides a convenient solution for experimentally determining the internal resistance and the EMF of a cell.
The unit requires connection to a 6V DC source of EMF, a voltmeter and an ammeter.
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.
