1. A number 12 copper wire has a diameter of 2.053 mm. Calculate the resistance of a 37.0 m long piece of such wire. (Use 1.72×10-8 Ωm for the resistivity of copper.) Use the formula for resistance remembering that the diameter is specified rather than the radius. 2. For safety, the National Electrical Code limits the allowable amount of current which such a wire may carry. When used in indoor wiring, the limit is 20.0 A for rubber insulated wire...
