Question

The electric current passing through a metallic wire produces heat because of ________.

• A. collision of the atoms of the metal with each other
• B. collision of the conduction electron with the atoms of the metallic wire
• C. collision of conduction electrons with each other
• D. none of the above

collision of conduction electrons with each other

When an electric current passes through a metallic wire, electrons move inside the wire and they collide with each other during their motion which produces heat in the wire.
