LED with the car battery. Is this possible?
You have to be careful, because a car battery is not normally 12V but a bit
over, like 13-14V (I think). Maybe a regulating circuit could be used?
It should.So if I hook up a circuit in parallel with the rest of the circuitry that
goes off the battery, and I place a resistor of 600OHMs and a single LED,
will it light up?
Does the size of the wire I use matter?
I don't think so, because the wire isn't carrying much current through it.
