HOW DO ELECTRIC HEATERS WORK?

A current passes through a wire that provides electrical resistance. This resistance converts all of the electrical energy into heat. That’s why energy efficient electric heaters are all 100% efficient. actually, it does turn into heat, eventually. The standing fans moves air molecules, and the increased friction between the air molecules turns into heat. It’s the law of entropy – all forms of energy tend to move to a more disorganized state, and heat is the most disorganized form of energy there is.
