As current flows through a uniform wire,the wire gets hotter because the electrons stop moving and therefore transform their lost kinetic energy into thermal energy in the wire.

Question

Quizplus · Accepted Answer

The statement is incorrect. Electrons do not stop moving when a current flows through a wire. In fact, they move with a certain average velocity known as the drift velocity. The friction between the moving electrons and the atoms in the wire leads to the transfer of energy and the production of heat, which increases the wire's temperature.
