Joule's law. Word Origin. noun Physics. 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.
Joule's laws are two: first about heatproduced 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}
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 happens for.
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 changes.
