Question
The heating element in an electric heater is made of
which element?ÂSolution
Nichrome • It is a metal alloy made up of around 20 percent of chromium and 80 percent nickel. • The key to the workings of an electrical heating element is the role of the nichrome in it. • Nichrome has fast emerged as the leading alloy to be used in terms of electrical heating elements. • For an electric iron heater element should have higher resistance, high melting point, and high specific heat. • An element should have high resistance so that it can hold its configuration in a high voltage current. It should have a high melting point such that it can sustain high temperatures.
