The drift speed of charge carriers in a conductor carrying current / is ngA where n is the number of mobile charge carriers per unit volume, q is the magnitude of the charge on each carier, and A is the cross-sectional area of the conductor. The transmission line has a diameter of 2.00 cm so that its radius is r- 1.00 cm - 1.0 x 10 m and so that its cross-sectional area is A- nr - n(1.0 x 10-2 m)? = nx 10- m2, In metallie conductors, the mobile charge carriers are electrons, each with a charge of magnitude q - e. We are given the density n of free electrons in this copper material per unit volume. Thus, the drift speed of the electrons is ngA x 102 (1.60 x 10-19 C( x 10- m) x 10 4 m/s.
