Lost Volts

Description

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.
