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 … WebThe electric power P is equal to the energy consumption E divided by the consumption time t: P is the electric power in watt (W). E is the energy consumption in joule (J). t is the time in seconds (s). Example Find the electric power of an electrical circuit that consumes 120 joules for 20 seconds. Solution: E = 120J t = 20s

WebThe watt (symbol: W) is the SI derived unit of power, equal to one joule per second. A human being climbing a flight of stairs is doing work at the rate of about 200 watts; a trained athlete can work at up to 900 watts for short periods. Webwatt-hour (Wh): The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time . The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. WebApr 10, 2024 · Power is the rate at which energy is transferred or Converted or the rate of doing work. SI Unit of power is Watt; 1 Watt = 1 J/s = 1 kg -m 2 /s 3. 1 watt is equal to 1 joule of work done in 1 second. Watt is named after the famous inventor James Watt.
