WebThe length is 12 meters. 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. WebA 12-gauge wire is wider than 14-gauge wire and thus has less resistance. The lesser resistance of 12-gauge wire means that it can allow charge to flow through it at a greater …
