Question

Q. Why are the heating elements of electric toasters and electric irons made of an alloy rather than a pure metal ?​

Answer 1

because alloys provide more resistance which in turn provide more heat,

Answer 2

Explanation: Heating elements of electric toasters and electric irons are made of an alloy because of the following reasons :-

• Alloys do not burn (or oxidise) easily at high temperatures.

• They have high resistance, so when even a small magnitude of current passes through them, they get heated up enormously.

• They have high melting points.
