Question

state joule's law in mathematical form​

Answer 1

Joule's Law of heating

$h = {i}^{2} rt$

i - current through resistor

r - resistance of the resistor

t - total time of current flow

Answer 2

Answer:

Joule's law of heating :- It states that when the heat is produced in a conductor it is directly proportional to the square of the current flowing through it it's resistance and the time taken by the current to passed through the circuit.

Mathematically it can be expressed as :-

H = Heat

I = Current

R = Resistance

$\mathrm{H = I^2Rt}$

S.I unit :- Joules (J)

Current :- It is defined as the rate of flow of electric charge through any section of the conductor.

Resistance :- It is neither a conductor or a insulator but it resist the flow of charge in the circuit.
