Item no.: XLE110010
• 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 requires connection to a 6V DC source of EMF, a voltmeter and an ammeter (these are not supplied but there are a range of Lascells items that you could use – see the Accessories list for details).
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.
