Question

state and explain the jouls law of heating

Answer 1

the rate at which heat is produced by current in any part of an electric circuit is directly proportional tothe resistance and the square of current

Answer 2

joules law of heating states that the heat developed on the conductor is directly proportional to the current flowing through it and the pd across two ends of the conductor.
H = VI

W=E/T
energy done in the form of heat
H/T=W
H=PT
H=VIT
