How does conduction, convection and radiation work to transfer heat from an electric radiator in your bathroom?
1 Answer
Refer to explanation.
Explanation:
An electric radiator is a home appliance that works by converting electrical energy to heat. There is a resistor present in the heater. Due to the large resistivity of this resistor, when current passes through it, the resistor heats up quickly.
As the resistor warms up, the interior of the radiator gets heated, which means air is warmed and it circulates around the room through convection. Simultaneously, the surface of the radiator gets hot, which releases heat out as radiation.
Conduction also occurs in this, but I don't believe it is significant in heat transfer. It is highest near the resistor, which can achieve very high temperatures.
Do note that I am no expert on electric radiators! This is just my understanding of the matter.
