Question

The conduction electrons in a cylindrical, current-carrying wire have a drift velocity of 0.35 mm/s. The wire has a radius of 1.0 mm and contains 8.6 x 10²⁸ conduction electrons per m³. What is the current in the wire? (The magnitude of the charge of an electron is 1.602 x 10^-19 C.)

a.

3.0 A

b.

6.0 A

c.

9.0 A

d.

12 A
