Question

Should the heating element of an electric iron be made of iron, silver or nichrome wire? Justify giving three reasons?

Answer 1

Nichrome wire should be used as the heating element in an electric iron. The reasons are mentioned below:

• High resistivity thus ensuring the wires to heat up faster.


• High melting point which does not melt the wire with thedue to an increase in temperature


• High specific heat which provide enough heat to the element.

Answer 2

Nichrome

Nichrome of an electric iron be made of iron, silver or nichrome wire
-----------------------------------------------

Yes, The heating element of an electric iron be made of iron, silver or nichrome wire because of the Following reasons

:-

1) Higher and specific electricity provide the Heat to the Device

2) They are faster, and they have Long capacity to work.

3) Electricity can be easily passed.

4) We can't get current because they are well constructed

5) They have the High Meeting point and This High melting point didn't increase the temperature.
