Joule's first law, also known as theJoule–Lenz law, states that the power of heating generated by an electrical conductor is proportional to the product of its resistance and the square of the current: P ∝ I 2 ⋅ R {\displaystyle P\propto I^{2}\cdot R}

Answer:
joules law of heating :
according to this law ,
the heat produced in a resistor is directly proportional to
the square of current flowing in the resistor
the resistance for a given current
time taken for the current to flow through the resistor
H proportional to I^2
R
