The Electric Power or Energy In simple words, It is the rate at which electrical energy consumed or absorbed or transferred by an electrical circuit. Electric Power or Electrical energy can be provided by batteries or Electric Generators & Power can be consumed by the load connected to the circuit. In other words, Electric Power is also defined as the product of voltage and current in an electric circuit. The SI unit of Electric Power is watt and which means one joule per second. For the measurement of electric power or connected load, we used the watt-meter. The electrical power measured in KWh in energy meter in which Units counts as per connected load.  If 1000 watts consumed in one hour by connected load then it will be 1 unit in energy wattmeter. We can say 1 KWh is equal to 1 unit. There are three types of Electric Power:  (i) Actual or Real Power  (ii) Apparent Power (iii) Reactive Power (i) Actual or Real Power:  Actual power is the product of the...
