Answer 1

Electric heater works on the principle of Joule's Law of Heating and it normally made up of an alloy of Nickel (80%) and Chromium (20%) called Nichrome,it has a high resistance.

Answer 2

An alloy of nickel and chromium is used as the heating wire in a heater.

Explanation:

• the characteristics of a heating wire is that it should have high melting point.

• In addition to this it should also have high resistance because resistance is directly proportional to the amount of heat which is generated.

• For this process the ideal wire should be made up of an alloy consisting of 80% of Nickel and 20% of chromium.

• In short we also referred this type of whereas nichrome wire.
