If a certain amount of power is dissipated for a given time, then ENERGY is dissipated. Energy (power x time) is measured in Joules and by including time (t) in the power formulae, the energy dissipated by a component or circuit can be calculated. Energy dissipated = Pt or VIt or V2t/R or even I2Rt Joules.
