A number 16 copper wire has a diameter of 1.291 mm. Calculate the resistance of a 43.0 m long piece of such wire. (Use 1.72x 10-8 sm for the resistivity of copper.) 5.650×10-1 Ohm You are correct. Previous Tries 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 6.0 A for rubber insulated wire of that size. How much power would be dissipated in the wire of the above problem when carrying the maximum allowable current? 2.034×101 w You are correct. Previous Tries What would be the voltage between the ends of the wire in the above problem? Submit Answer Tries 0/20 What is the current density in the wire when it is carrying the maximum allowable current? (Current density is the current in the wire divided by the cross sectional area of the wire.) Submit Answer Tries 0/20 What is the drift velocity of the electrons when the wire is carrying the maximum allowable current? (The density of electrons in copper is 8.47×1028 m-3.)
