How much resistance in a wire

WebSep 12, 2024 · The resistance can be found using the length of the wire L = 5.00m, the area, and the resistivity of copper ρ = 1.68 × 10 − 8Ω ⋅ m, where R = ρL A. The resistivity and … 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.
