Question

Name two special characteristics of material used in electric heater devices

Answer 1

Answer: substances or metals like copper are mostly used to make electrical heater as it is a very good conductor of electricity and heat.

Answer 2

Two special characteristics of the material used in electric heater devices are:

• The melting point of the materials used in electric heater devices is high. Materials like Nichrome is used because it has high resistance and can produce more heat. Hence, it can be used for heating at high temperatures without the fear of melting.
• Cupronickel has high resistance to oxidation and corrosion. As it is ductile, Cupronickel is used in making electric heating devices.
