The figure shows wire section 1 of diameter D 5.50R 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 1.90 m shown in section 2 is 9.00 V. The number of charge carriers per unit volume is 8.90 x 102 m3. What is the drift speed of the conduction electrons in section 1?
