Question

STATE JOULE'S LAW OF HEAT.

Answer 1

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 2

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
