Question

With what do electrons continuously collide in a conductor?

Options

• Only free electrons moving in the same direction

• Fixed positive ions of the lattice and imperfections present in the material

• The cross-sectional area of the conductor

• Only the electric field

Answer 1

Electrons collide with fixed positive ions of the lattice and with imperfections in the material. These collisions prevent motion along a perfectly straight path for long intervals.
