Consider electrons flowing in copper.

(a)

Compute the average time between collisions τ for free electrons in copper.

(b)

Due to quantum mechanical effects, electrons in copper have a speed of about 106 m/s at room temperature. Show that electrons moving at such speeds will travel an average distance of 25 nm between collisions.

2 Drift Velocity The average velocity of electrons in a material with a scattering time τ is vd = eE me τ. The scattering time also determines the resistivity of the material: ρ = me ne2τ . Here, n is the free electron density of the material — the number of free electrons per cubic meter. (a) Estimate the free electron density in copper. There is one free electron per copper atom. The mass density of copper is 8.92 g/cm3...

The point of this problem is to show how slowly electrons travel on average through a thin wire, even for large values of current. A wire made from copper with a cross-section of diameter 0.740 mm carries a current of 13.0 A. Calculate the "areal current density"; in other words, how many electrons per square meter per second flow through this wire? (Enter your answer without units.) The density of copper is 8.99 g/cm3, and its atomic mass is 63.8....
