Question

electric room heater

Answer 1

Answer:

An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy.

Answer 2

Answer:

They work on the principle of heating the room through convection technology where a coil or a panel is used for heating. A fan/ blower is blown towards the heat panel which spreads warm air in the entire room. These room heaters spread heat through a metallic coil which glows upon being heated electrically.
