WebElectric Power. In physics, electric power measures the rate of electrical energy transfer by an electric circuit per unit of time. Denoted by P and measured using the SI unit of power which is watt or one joule per second. Electric power is commonly supplied by electric batteries and produced by electric generators. Table of Contents: 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.
