Question

State joules law and explain it.

Answer 1

Answer:

hello :D

Joule's law of heating states that when a current 'i ' passes through a conductor of resistance 'r' for time 't' then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time

Answer 2

$\huge\rm\underline\purple{Answer:-}$

joules 1st law :

a physical law expressing the relationship between the heat generated and current flowing through a conductor

joules 2nd law :

the internal energy of an ideal gas is independent of its volume and pressure, depending only on its temperature. ..

Explanation :

the principle that the rate of production of heat by a constant direct current is directly proportional to the resistance of the circuit and to the square of the current. the principle that the internal energy of a given mass of an ideal gas is solely a function of its temperature.
