the heating element is gone out
The wire in the cord has much lower resistance than the heating element. The heating element is a resistive or resistance heating element. Resistance in the quality of a substance or material that causes it to limit current flow, and it get heated up in the process. The heating element has all but the smallest fraction of the resistance in the circuit, so the heat, that thermal energy that get the water hot, is generated by the resistance of the heating element.
It is heat transfer by radiation.
It could be caused by a damaged heating element. You should have the heating element checked by a professional. Try cleaning the dryer first. Remove lint clogging the exhaust vent. Overheating in the washer might cause the heating element to shut off safely. Also check if the dryer is plugged correctly.
because the heating element is made of iron and iron glows red-hot when exposed to substantial heat which is triggered using electricity, and therefore the iron is hot (and therefore you see the red light).
we wont use copper as a heating element because it expands on heating and it can effect the thermostat
no because an heating elementcan cause electric shock.
Conduction because its the transfer by touch
the element has a open in it !
Yes heating element is burner assembly.
Heating element is the main part of the ironbox which gets heated as current passes through it. We have to use the material for heating element with features such as: 1) high melting point 2) high specific resistance 3) not easily oxidised. (most important point) Hence the alloy NICHROME ( nickel and chromium) is used for heating element because it is not oxidised even at high temperatures.
Positive temperature coefficient heating element. Resistivity grow larger with higher temperatures so the heating element should be self regulating.
Thermal energy exists in materials raised to a high temperature, because they can then transfer this energy to materials at lower temperatures. For example , heating radiators transfer energy to the building they are in. Electric energy is basically the movement of free electrons in a conductor, which can then do work such as turn an electric motor, or indeed produce thermal energy in a heating element,
where is the heating element on a kenmore series 400
Element, meaning a heating element and not a natural element. The heating element is made by wrapping 'nichrome' wire around a flat sheet of Mica composite board. This then glows red hot, when mains electricity is applied to it. Nichrome is an alloy of Nickel and chromium. Chosen because it has electrical resistance and can stand repeated heating and cooling without melting.
limitation of heating element
Because metals are good heat conductors !
