Question

state joules principal of heating​

Answer 1

Answer:

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.Explanation:

Answer 2

Answer:

Joule’s first law

The joule’s first law shows the relationship between heat produced by flowing electric current through a conductor.

Q = I² R T

Where,

Q indicates the amount of heat

I show electric current

R is the amount of electric resistance in the conductor

T denotes time

• The amount of generated heat is proportional to the wire’s electrical resistance when the current in the circuit and the flow of current is not changed.

• The amount of generated heat in a conductor carrying current is proportional to the square of the current flow through the circuit when the electrical resistance and current supply is constant.

• The amount of heat produced because of the current flow is proportional to the time of flow when the resistance and current flow is kept constant.
