The gure shows wire section 1 of diameter D1 = 5.00R and wire section 2 of diameter D2 = 4.00R, 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 V along the length L = 2.30 m shown in section 2 is 11.0 IN. The number of charge carriers per unit volume is 9.00 x 1028 m'3. What is the drift speed ofthe conduction electrons in section 1? (1)
