Question

what is the joules hearing effect of current,service its expression​

Answer 1

Answer:

hey mate !!!

Jule's law :-

according to this law.

the heat produced by register is :-

1) directly proportional to a square of current flowing through the resistance.

-----------(1).

2) directly proportional to resistance for given current

=>>H is directly proportional to R -----(2)

3) directly proportional to the time , for which current is flowing .

H is directly proportional to t --------(3)

from first second and third equation we get.

from ohm' s law we have also H = IVT

hope it helps!!!

thanks
