Question

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.

Answer 1

Answer:

joule's law of heating :

Explanation:

it states that when a current 'i' flows through a conductor having resistance 'R' for time 't', then the heat produced (H) in it is directly proportional to the square of current, resistance of conductor and time.

mathematically it is H=$i^{2}$Rt
