WebFeb 11, 2024 · Joule’s Law of Electric Heating. From Eq. (1) the energy expended or heat generated in joules when a current of I amperes flows through a resistance of R ohms for t seconds is given as. H = I 2 R t joules. The above expression is known as Joule’s law, which states that the amount of heat produced in an electric circuit is. WebWe’ll shortly derive a more general expression for CP − CV, but the correction for nonideality will obviously be quite small. 10.3 The Joule-Thomson Experiment The experiment is also known as the Joule-Kelvin experiment.
