Question

State and prove the joule's law of heating?

Answer 1

H=I^2RT here H is heat
I is current
R is resistance
T is time

Answer 2

Answer:

joules law of heating stater that is current (1) is passed through a conductor of resistance (R)for time (T)then the heat produced will be equal to the produce will be equal to the produce of square of current......resistance and time in this way...

after combining equation (1) (2) and (3)

'H' directly proportion to i2 , R.T

H=K.I2. RT

K=1

H=12 ×RT
