Question

= 3. How is the heat produced by an electric current related to resistance and the magnitude of the current?​

Answer 1

Answer:

When an electric current flows through a conductor or in a wire, some of it's electrical energy gets converted into heat energy, which is called the heating effect of current.

Also, a thick wire has less resistance whereas a thin wire has more resistance. Greater the magnitude of current passed through a given wire, greater will be the heat produced in it. A small current passing in a wire produces less heat but a large current passing through the same wire produces much more heat.
