although copper is a good conductor of electricity, it cannot be used to make the element of heating devices. justify by giving suitable reasons. (2 marker question)​

Answer 1

Answer:

1. it is because it gets oxidised easily.This is because it becomes red hot and cannot be used for making heating appliances
2. Also,resistance is inversely proportional to the current.

• now copper is a metal.it is a good conductor of electricity hence, receives higher current.Therefore the amount of heat produced is less.
• That's why it is not used for making of heating devices

Explanation:

Resistance is directly proportional to heat

and copper is not highly resistant
