Notice, we're asking, what's the resistance of the wire itself? Now there's not really a quote-unquote resistor in here. But every piece of wire's gonna offer some resistance. And this formula applies just as well to a piece of wire as it does to a resistor. So, the length of the wire's 12 meters, and the diameter is 0.01.

WebWire gauge - The wire gauge, or size of the wire, also determines how much resistance the wire has. The larger the wire, the less resistance. The smaller the gauge, the larger the wire -- so a 16-gauge wire is bigger than a 24-gauge wire. Wire gauges go all the way down to zero, which is also called 1/0 (one aught).
