Question

State whether the following statement is True or False.

When electric energy is converted into heat, it is called Joule’s heating.

Answer 1

This statement is true.

Explanation:

When electrical energy is converted into heat energy due to the resistance of a conductor, the phenomenon is called Joule’s heating or the heating effect of electric current.

According to Joule’s law of heating,

\[ {H=I^2Rt} \]

where \(H\) is the heat produced, \(I\) is the current, \(R\) is the resistance, and \(t\) is the time.
