Hi, I am currently in the process of doing a school project on circuits.
What I am about to do is very simple, but the only problem is I don't know how to go about doing it.
I need to light a 12V light bulb using a battery. However the length of the wire which connects the battery to the bulb has to be 100 metres copper wire (diameter 1mm).
How do I go about making this circuit bearing in mind that it must work out in the field where there is no electricity supply (only batteries).
Thanks.
Kate
