In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.

Electric power is the rate of transfer of electrical energy within a circuit. Its SI unit is the watt , the general unit of power , defined as one joule per second . Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively.
Power, in science and engineering, time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t—or W/t. A given amount of work can be done by a low-powered motor in a long time or by a high-powered motor in a short.

Power is the rate at which energy of any type is transferred; electric power is the rate at which electric energy is transferred in a circuit. In this section, we’ll learn not only what this means, but also what factors determine electric power.
Intro. Power is the rate at which work is done or the rate at which energy is transfered from one place to another or transformed from one type to another. units. watt is the unit of power. From the basic definition… any units of work (or energy) and time can be used to generate a unit of power.
