electric power
The rate at which electric energy is consumed or delivered by an electric device or system, equal to the product of the current and the voltage drop.

electric power
As energy is the capacity for doing work, electric energy is represented by electricity in motion against a resistance. This possesses a species of inertia, which gives it a species of kinetic energy. To produce such motion, electro- motive force is required. The product of E. M. F. by quantity is therefore electric energy. (See Energy, Electric.)
Generally the rate of energy or power is used. Its dimensions are
( ( (M^.5)*(L^.5) ) / T )
*
( ( (M^.5) *(L^1.5) )/( T^2) )
(intensity or current rate)
*
(electro-motive force or potential)
= (M * (L^2) ) / (T^3), which are the dimensions of rate of work or activity. The practical unit of electric rate of energy or activity is the volt-ampere or watt. By Ohm's law, q. v., we have C = E/R (C = current; E = potential difference or electro-motive force; R = resistance.) The watt by definition = C*E. By substitution from Ohm's formula we deduce for it the following values: ((C^2) * R) and ((E^2) /R). From these three expressions the relations of electric energy to E.M.F., Resistance, and Current can be deduced.

Electric power is defined as the amount of work done by an electric current, or the rate at which electrical energy is transmitted. The SI unit of power is the watt.

When electric current flows in a circuit with resistance, it does work. Devices convert this work into many useful forms, such as heat (electric heaters), light (light bulbs), motion (electric motors) and sound (loudspeaker).
