Righto. Thanks

Thanks for the reply. worked out what the problem was. This is very strange, but i was using a Nokia Charger which provides 8.78V with nothing connected., but for some reason when you measure the drops across everything connected (resistors) in series, it looses a volt or two! Any idea why? thanks

Im currently reading a book on electronics, that says that the sum of the Voltage drops across all components tied in series should equal the voltage of the battery. However i tested cicuit on a breadboard with a led and a resistor, and measured the drops accross each and added them together. They did not add up to the supply voltage. Anyone have any ideas? Thanks very much. :)
