4.6: Dissipation of Energy
When a coulomb drops through a volt, it loses potential energy 1 joule. This energy is dissipated as heat. When a current of (I) coulombs per second falls through a potential difference of (V) volts, the rate of dissipation of energy is (IV), which can also be written (by making use of Ohm''s law) (I^2R text{ or }V^2/R).
