प्रश्न
Name three main characteristics of an heating element.
उत्तर
The three main characteristics of an heating element are:
(i) It should have a high resistance so that a major amount of electric energy is converted into heat energy.
(ii) It should not get oxidised easily up to a temperature of 1000°C.
(iii) It should have a high melting point and a low thermal Expansion so that it does not get loosened on getting heated.
