State the law which governs the amount of heat produced in a metallic conductor when current is passed through it for a given time. Express this law mathematically.

When current flows through a conductor for a unit time, it produces some amount of heat. This phenomenon is known as the heating effect of electric current.

The heat (H) produced during the heating effect of electric current is given by the formula:



Here, I = Current


R = Resistance of conductor


t = time


The SI unit of the heat produced is Joules (J).
