Electric utilities measure energy using an electricity meter, which keeps a running total of the electric energy delivered to a customer. Electric heating is an example of converting electrical energy into another form of energy, heat. The simplest and most common type of electric heater uses electrical resistance to convert the energy. There ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project.Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job".
A toaster is a great example of a single-phase load that might appear in a residence. Toasters typically draw 2 to 10 amps at 110 to 260 volts consuming around 600 to 1200 watts of power. Power systems deliver energy to loads that perform a function. These loads range from household appliances to industrial machinery.
The following are examples of representations of components by way of electrical elements. On a first degree of approximation, a battery is represented by a voltage source. A more refined model also includes a resistance in series with the voltage source to represent the battery's internal resistance (which results in the battery heating and ...
Electric utilities measure power using electricity meters, which keep a running total of the electric energy delivered to a customer. Unlike fossil fuels , electricity is a low entropy form of energy and can be converted into motion or many other forms of energy with high efficiency.
An electrical component that stores energy in an electric field. capacitor-input filter A power supply network where a capacitor is the first element following the rectifier. capacitor voltage transformer In electrical power systems, an instrument transformer for measuring voltage that uses a capacitive voltage divider. capacity factor
