What principle do electric resistance heaters operate on?

Electric resistance heaters operate on the principle of converting electrical energy into heat. This process occurs when an electric current passes through a resistive material within the heater. This material resists the flow of electricity, and as a result, it generates heat due to the resistance encountered by the electrons moving through it. The heat produced is then transferred to the surrounding air or objects, warming the space or the items in contact with it.

This principle is fundamental to the operation of electric resistance heating technologies, including baseboard heaters, wall units, and portable electric heaters. The effectiveness of these heaters relies on the efficiency of electricity being converted into thermal energy, which is essential for achieving the desired heating outcomes in various environments.
