Problem Extending power wire

[awsomedude]

I have a small computer in my car, and I ran 2 10 foot wires from the mother board to the switch. It does not work, but if shorten them down to like 4 inches it works fine. Any ideas? Is there such thing as a power switch wire that is to long?

Time to go read about resistance, current, and basic circuts.

you'd probably be ok if your wire was 20 guage or lower but that would be some thick wires for what you're doing.
