Question

What do you mean by $H=I^{2}RT$?

Answer 1

Meaning of $H=I^{2}RT$:

1. The joule’s first law shows the relationship between heat produced by flowing electric current through a conductor.
2. $Q=I^{2}RT$, here $Q$ is Amount of heat,$I$ is Electric current, $R$ is Amount of electric resistance in the conductor and T is time.
3. The amount of heat produced is proportional to the electrical resistance of the wire when the current in the circuit and the flow of current are not changed.
4. When the electrical resistance and current supply are constant, the amount of heat generated in a conductor carrying current is proportional to the square of the current flow through the circuit.
5. When the resistance and current flow are held constant, the amount of heat produced by the current flow is proportional to the flow time.
