Nichrome is used to make electric heater . Why ?

Question

Answer

Because it have high melting point.it does not melt even at high temperatures for example in heaters.

Answer

Because it has high melting point and has high resistivity

Answer

Why is Nichrome Used to Make Electric Heater?

Nichrome is a popular material used for making electric heaters. This is due to its unique physical and chemical properties which make it an excellent choice for heating elements. In this article, we will discuss the reasons why Nichrome is used to make electric heaters.

High Melting Point

Nichrome has a very high melting point, which makes it ideal for use in electric heaters. It can withstand temperatures of up to 1400 degrees Celsius without melting or deforming. This makes it suitable for use in high-temperature applications, such as electric furnaces and ovens.

Low Temperature Coefficient of Resistance

The temperature coefficient of resistance is a measure of how much the resistance of a material changes with temperature. Nichrome has a low temperature coefficient of resistance, which means that its resistance remains relatively constant even at high temperatures. This makes it ideal for use in electric heaters, where a stable resistance is essential for accurate temperature control.

High Electrical Resistance

Nichrome has a high electrical resistance, which means that it can convert electrical energy into heat very efficiently. This property makes it an excellent choice for heating elements in electric heaters. The high electrical resistance of Nichrome also means that it can be used to make wires of a very small diameter, which can be useful in applications where space is limited.

Corrosion Resistance

Nichrome is highly resistant to corrosion, which makes it suitable for use in harsh environments. This property is particularly important in applications where the heater is exposed to moisture or chemicals, such as in industrial processes.

Conclusion

In conclusion, Nichrome is an excellent material for making electric heaters due to its high melting point, low temperature coefficient of resistance, high electrical resistance, and corrosion resistance. These properties make it an ideal choice for a wide range of applications, from electric ovens and furnaces to industrial processes.

Answer

Nichrome is used to make electric heater because it has high melting point

Answer

Because it is a alloy So , it has high melting point .

Answer

Nichrome (80%nickel and 20%chromium) is used for making electric heater because of its high resistivity, high melting and resistance to oxidation at high temperature.. So this is the reason why nichrome wire are used as coil in electric heater

Answer

High melting point and high resistivity

Answer

Since nichrome is an alloy, it provide more resistance compared to conductive metals like copper, silver. more the resistance, more collisions s in the wire, more the collisions, more heat produced thus nichrome wires are preferred compared to other metals in heating devices

Answer

As it is an alloy so its melting point  is high and since it has an higher resistivity so it can produce  a lot of  heat

Answer

Nichrome is used to make electric heater because the nichrome has comparatively a high resistance due to which it can heated up by passing electricity.
