WebMar 16, 2024 · Answer. The heating element of an electric heater is made up of alloys. Alloys have very high resistance, so when the current passes through the alloy, it blocks the current and doesn’t let it pass through it. Thus, the heating element becomes hot and glows red. On the other hand, the cords are made up of good conductors like copper. WebPTC heating elements are a type of thermistor. Properties [ edit] PTC heating elements have a large positive temperature coefficient of resistance, which means if a constant voltage is applied, the element produces a large amount of heat when its temperature is low, and a smaller amount of heat when its temperature is high. WebProperties of the element: The heating capacity of an element depends on three factors. They are, Material, Length, and Thickness of the coil These properties can vary depending on the requirements of heat.
