Question

Explain the joules law 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.

Answer 2

Joule's law of heating states that ,

When an electric current "i" passes through a conductor with resistance "r" in time "t" it produces heat "h" which is directly proportional to the square of current "i" , resistance and time .

Which can be expressed as ,

H is directly proportional to I²RT

Or H = I²RT

Where I is the current , r is the resistance and t is the time
