Please write your answers clearly. You have 15 minutes. A 100 m long and 3 mm diameter copper wire dissipates 1.1 W of power when a 0.5 V potential is applied. Copper has a Hall coefficient of 5.5 x 10‐11 m3A‐1s‐1. Calculate the (a) drift velocity, (b) mobility, (c) collision time, (d) thermal velocity, and (e) Hall field for a transverse magnetic field of 0.5 Tesla at 300K. (f) Which component (vth or vD) dominates the total electron velocity (vtotal = vth + vD)? Your calculations may be helpful in answering this question. ...
