What should be the characteristic property of the material used in making the heating element of electrical appliances?

The most important heating element characteristics are sufficient resistivity, high oxidation resistance, low-temperature coefficient of resistance, high toughness, and high melting point.

What should be the properties of the heating element used for resistance furnace?

Materials engineered to have properties suitable for resistance heating element applications must have sufficient internal electrical resistance, high melting point, and sufficient elevated temperature strength.

What property should a material possess to be used as a heating element in an electric heater?

The heating element of an electric heater is subjected to very high temperature ranges, so it must have the ability to withstand higher temperature ranges. Therefore, the heating element of an electric heater should have a high melting point.

Which property of a conducting wire is Utilised in making a heating element of a heater Class 10?

Answer: Hence, the nichrome wire is used as a heating element because it has high specific resistance. Thus, the correct option is C. Note: A nichrome wire is used as a heating element because of its high melting point and high resistivity (low conductivity) also.

What type of material is used in heating element?

Nichrome: Most resistance wire heating elements usually use nichrome 80/20 (80% Nickel, 20% Chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time.

What are the characteristics of the material for heating element?

The most important heating element characteristics are sufficient resistivity, high oxidation resistance, low-temperature coefficient of resistance, high toughness, and high melting point.

What should be the characteristics of a heating element?

1 Answer

  • (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.

Which material can be used as heating element and why?

The most common material used for the heating element is Nichrome. Nichrome is the alloy of the Nickel and chromium; in this alloy the nickel is 80% and the chromium is 20%. So, this alloy is called nichrome 80/20.

What is the resistance of a heating element?

A good element will have a resistance between 5 and 25 Ohms.

What are the properties of conducting?

The property of conductors to conduct electricity is called conductivity.

What are the properties of conducting wire?

General Science

the property of conducting wire that is utilised in making electric fuse is low melting point. generally fuse wire has low melting point because, when large amount of current passes through it, it melts in order to prevent overflow of current to devices.
