Question

The elements of electric heating device made up of a alloy rather than a pure metal

Answer 1

Because alloys have the following advantage over pure metals :

1. Alloys have high electrical resistivity than pure metal.

2. Alloys do not undergo oxidation easily even at high temperature.

So, elements of electrical heating devices are made of alloys rather than a pure metal.

$\bold\green{Your\:Answer:-}$

b) The conductors of electric heating devices such as bread toasters and electric irons are made of alloy because

◾resistivity of an alloy is more than that of metals.

◾It produces large amount of heat and do not burn easily.
