The electric current passes through a metallic wire produces heat because of

View answer and explanation

Correct option: D

collisions of the conduction electrons with the atoms of the metallic wire

Option D (collisions of the conduction electrons with the atoms of the metallic wire) is correct because the heat generated is due to the resistance encountered by electrons as they collide with the atoms in the wire.
