Question

what do you understand by the term heating effect of an electric current​

Answer 1

Answer:

The effect produced by the current in the form of heat when it passes through a conductor is called the heating effect of current.

Explanation:

Only conductors can allow the flow of electric current through them. Every conductor will have different resistances. A particular amount of heat will be generated when a current is passed through a conductor of resistance R. If I is the current passed through the conductor for a particular interval of time t, then the heat generated will be equal to the product of the square of the current, the resistance of the conductor and the time of flow of current through the conductor. It can be formulated as:

                                       H = I²Rt

This is known as Joule's law which explains the heating effect of electric current.
