Electric power (P size 12 {P} {} ) is simply the product of current times voltage. Power has familiar units of watts. Since the SI unit for potential energy (PE) is the joule, power has units of joules per second, or watts. Thus, 1 A ⋅ V = 1 W size 12 {"1 A " cdot V=" 1 W"} {}.

Electrical energy is energy that comes from moving electric charges. It can be produced through various means such as chemical reactions, like redox reactions, which generate an electric current.
For example, when a current flows in a conductor, electrical energy is converted into thermal energy within the conductor. The electrical field, supplied by the voltage source, accelerates the free electrons, increasing their kinetic energy for a short time.
Definition. Electrical power refers to the rate at which electrical energy is transferred or consumed in a circuit. It is measured in watts (W) and can be calculated by multiplying the voltage (V) across a device by the current (I) flowing through it.
