Determine the current density for copper wire

Reference no: EM13250531

(a) Estimate the drift speed for electrons in a copper wire of 1 mm diameter that carries a current of 100 mA. Copper has about one free electron per atom available to carry charge and has a mass density of 8.92 g/cm3 and a molecular weight of 53.5 g/mol.

(b) Determine the current density, resistance and electric for the copper wire, if the wire is 10 m long.
