Question

Heat is produced by rubbing friction is it possible that when we turn on electric current in electrical heater, induction and other appliances the molecules of wire (nichrome wire) and the molecules of electric current (electron , proton and neutron ) will rubbing continuously with each each other when we plug the switch and on it there is a friction between molecules of wire and the molecules of electric current produce heat .

Answer 1

The molecules help in transportation of heat. But they don't produce heat.
