explain joules law of heating and mention the factors heat produced in resistors plz help
Answers
Answer:
Simply Joules Law of heat is :-
The amount of heat produced in a current conducting wire, is proportional to the square of the amount of current that is flowing through the wire, when the electrical resistance of the wire and the time of current flowing are constant.
Explanation:
(Simply heat generated is due to flow of Current)
The heat generated due to the flow of current is proportional to the time of current flowing, when the electrical resistance and the amount of current is constant
Explanation:
Joule's law of heating states that, when a current 'i ' passes through a conductor of resistance 'r' for time 't' then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.
