WebElectric power is transmitted by overhead lines like these, and also through underground high-voltage cables. 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.
Power (physics) - Wikipedia
WebIn 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. [1] [2] [3] Power is a scalar quantity.
What is a Watt? | Electricity Fundamentals
WebA watt is a unit of power, named after engineer James Watt, which measures the rate of energy transfer. A watt, in electrical terms, is the rate at which electrical work is done when one ampere (A) of current flows through one volt (V). Formula: W= A* V . Whenever current flows through a resistance, heat results. This is inevitable.
