The figure shows wire section 1 of diameter D,-5.50R and wire section 2 of diameter D2-3.00R, connected by a tapered section. The wire is copper and carries a current. Assume that the current is uniformly distributed across any cross-sectional area through the wire's width. The electric potential change Valong the length L-1.50 m shown in section 2 is 13.0 μν. The nurmber of charge carriers per unit volume is 820x 1028 m3. What is the drift speed of the conduction...

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...
