Question

What do you mean by heating effect of electric current? What are the factors on which the amount of heat produced depend on?

Answer 1

Explanation:

When an electric current passes through a conductor (like a high resistance wire) the conductor becomes hot after some time and produces heat. This is called heating effect of Electric Current. Example 1. A bulb becomes hot after its use for some time.This is because of heating effect of electric current.

List its four applications in daily life. Ans. When an electric current is passed through a high resistance wire, like nichrome wire, the resistance wire becomes very hot and produces heat. This effect is known as heating effect of current or Joule's law of heating.
