Thomson effect is caused

Options

Adue to both A and B
Bdue to A but not due to B
Cdue to B but not due to A
Dneither due to A nor due to B

Correct answer

A. due to both A and B

Step-by-step solution

Thomson effect is the evolution or absorption of heat when an electric current passes through a single conductor having a temperature gradient along its length. This effect arises because the charge carriers at different temperatures have different kinetic energies and different concentrations. When an electric current flows, the charge carriers move from a region of one temperature to a region of another temperature. In order to attain thermal equilibrium with the lattice at the new temperature, they either absorb
