 P: 81 1. The problem statement, all variables and given/known data Calculate the resistance per meter at room temperature of a constant wire if diameter $$1.25mm$$. The resistivity of constant a at room temperature is $$5x10^-7\Omega{m}$$ 2. Relevant equations I'm not sure, but I think this is the right formula: $$R = \frac{Pl}{A}$$ 3. The attempt at a solution $$Area = \pi \times \left(\frac{1.25 \times 10^{-3}}{2}\right)^2$$ $$A = 1.2 \times 10^{-6} m^2$$ What is Pl?
 P: 13 P is the resistivity and L is the length of the wire, so you are really solving for R/L
