Question

heat produce in an electric device is depend upon​

Answer 1

$\huge\mathfrak{\blue{\underline{\red{Answer}}}}$

The resistance, R of the conductor. A higher resistance produces more heat. The time, t for which current flows.

Answer 2

When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors:

The resistance, R of the conductor. A higher resistance produces more heat.

The time, t for which current flows. The longer the time the larger the amount of heat produced

The amount of current, I. the higher the current the larger the amount of heat generated.
