Question

Drift velocity and electric field intensity in conductors. A copper conductor with conductivity σ = 5.7 X 10⁷ S/m carries a current of 10 A. The conductor has a diameter of 2 rom. Calculate:

(a) The electric field intensity inside the conductor.

(b) The average drift velocity of electrons in the conductor assuming a free electron density of 8 x 10²⁸ electronslm³.
