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...

The resistance R of a wire of length l and uniform area of cross-section A is given by R = rhol/A, where rho is the resistivity of the wire. You melt the wire and recast it to have a new length l' = 10l (keeping the volume V = Al of the wire constant). What is the new resistance of the wire, if the original resistance of the wire was 100.0 Ohm.
