1. (General Physics) physics the principle that the heat produced by an electric current is equal to the product of the resistance of the conductor, the square of the current, and the time for which it flows
2. (General Physics) thermodynamics the principle that at constant temperature the internal energy of an ideal gas is independent of volume. Real gases change their internal energy with volume as a result of intermolecular forces
