Electric Power: Formula, Unit, and How to Calculate

Electric power is the ability of an electrical voltage source to perform work per unit of time. Electronic equipment requires electrical energy to operate by transforming it into another form of energy. The greater the amount transformed in a short time, the greater the power. It is calculated by dividing the transformed electrical energy by the time interval. In the generator, it is important to know the useful and dissipated power to obtain efficiency through the product of the potential difference by the current.
