Power is the total work completed over a predetermined period of time. It is a measure of how much energy is used up each unit of time.
The number of tasks finished in a specific length of time is a definition of power. The SI unit of power is the watt (W), which is generated from joules per seconds (J/s). A unit of measurement known as "horsepower" is used to quantify how powerful vehicles and some other machines are (hp).
Electricity is used by people to run appliances, computer, electronics, manufacturing, and public transit systems as well as for lighting, warmth, cooling, and refrigeration. French and Raven (1959) proposed five power relationships (or bases of power): referent, competent, legitimate, rewarding, and coercive.
