Science P5.35 Electric wire, like that in the photo, is a cylindrical conductor covered by an insulat- ing material. The resistance of a piece of wire is given by the formula where p is the resistivity of the conductor, and L, A, and d are the length, cross- sectional area, and diameter of the wire. The resistivity of copper is 1.678 × 10-8 Ω m. The wire diameter, d, is commonly specified by the...
