Question

what is joule law of heating​

Answer 1

Answer:

The heat which is produced due to the flow of current within an electric wire, is expressed in unit of Joules.

Answer 2

Answer:

Joule's law of heating states that heat released by conductor is:-

1)Directly proportional to square of current(I) flowing through it.

[R and t constant]

2)Directly proportional to its resistance(R).

[I and t constant]

3)Directly proportional to the time(t) current is passed through it.

[I and R constant]

By changing sign of proportionality to equal to

H= I²Rt
