what is joules law of heating
Answers
Joule's laws are two: first about heat produced by an electric current, and second about how the energy of a gas relates to pressure, volume and temperature.
Joule's first law shows the relation between heat generated by an electric current flowing through a conductor. It is named after James Prescott Joule and shown as:
{\displaystyle Q=I^{2}\cdot R\cdot t} {\displaystyle Q=I^{2}\cdot R\cdot t}
Where Q is the amount of heat, I is the electric current flowing through a conductor, R is the amount of electric resistance present in the conductor, and t is the amount of time that this happen
Joule's second law says that the internal energy of an ideal gas does not change if volume and pressure change, but does change if temperature change......
Hope it may help U mark me as brainlist....
It states that the square of current which passes through the conductor in one second and the resistance which act upon are directly proportional to the heating of the conductor .
