Web18 sep. 2015 · Using the passive sign convention for all elements, the law of conservation of energy (in terms of power) of a lumped isolated circuit can be stated as follows (for a reference, read section 1.5 of Fundamentals of Electric Circuits [5th ed.] by Alexander and Sadiku): \$\displaystyle\sum p_\text{consumed}(t) = 0 \text{ W}\$ WebEnergy and power are linked by an equation. If the power of an appliance is known, the energy transformed at any given time can be calculated by the following equation. For example, if a 500 W heating element is switched on for 10 seconds. The energy transformed = 500 W × 10 s = 5000 J. So the heating element radiated 5000 J of thermal energy.
