![]() Once converted from potential energy, electrical energy can always be called another type of energy that is heat, light, motion, etc. Thus all electrical energy is potential energy before it is delivered to the end-use. At the point that this electric potential energy has been converted to another type of energy, it ceases to be electric potential energy. This energy is supplied by the combination of electric current and electric potential or voltage that is delivered by an electrical circuit. When used loosely, electric energy refers to energy that has been converted from electric potential energy. Download Torque Unit Converter our powerful software utility that helps you make easy conversion between more than 2,100 various units of measure in more than 70 categories. Electrical energy is energy derived from electrical potential energy or kinetic energy. A watt measures rates of power over a time period. Let’s start with the basics- A watt (W) is a unit of Power, and power is the rate at which energy is produced or consumed. We usually pay for our electrical energy based on the amount of kilowatt hours (kWh) used - this is the equivalent to 1 kW of power expended over 1 hour of time. Electric utilities measure energy using an electric watt meter, which keeps a running total of the electric energy delivered to a customer. Electrical energy is usually sold by kilo watt hour that is 1 kWh = 3.6 MJ which is the product of the power in kilowatts multiplied by running time in hours. A watt (W) measures the rate at which energy is produced or consumed. ![]()
