Answer 2

Answer:

• The two common materials used as heating elements are Nichrome and Cupronickel.

Explanation:

• Heating occurs when the electrical energy is converted into heat energy by the use of these heating devices like Room heater, hair dryer, etc.

• For this heating effect, the resistance of the materials should be very high, therefore generally alloys are used as heating materials.

• The most common among them are Nichrome and Cupronickel.

• Nichrome is an alloy made up by mixing of Chromium and Nickel, which is present in the ratio of 1:4 respectively.

• Similarly, another alloy is Cupronickel which is mainly made up of copper and nickel, but small amount of iron and manganese are added to strengthen it and to increase its resistance.
