Question

1.Heating effect of electric current makes useful to make the coil of electric kettle​

Answer 1

Explanation:

A negligible heat is produced in the connecting wires of copper because copper has very low resistance. Similarly, when electric current is passed into an electric iron, the element of electric iron (made of nichrome coil) becomes red-hot and produces heat. This heat makes the button of electric iron hot.
