The idea of ports can be (and is) extended to waveguide devices, but a port can no longer be defined in terms of circuit poles because in waveguides the electromagnetic waves are not guided by electrical conductors. They are, instead guided by the walls of the waveguide. Thus, the concept...
An example of a power system is the electrical grid that provides power to homes and industry within an extended area. The electrical grid can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centers to the load cen...
The firstelectrical drivewas designed in Russia in 1838 by B.S. Iakobi, who used aDC electric motorpowered by a storagebatteryto propel a boat. Industrial use began around 1870. Today,electrical drivesare used in many applications. The very basic block diagram an electric drives is shown belo...
Use changeover contacts when you want to switch two circuits when the switch is operated. Switches in Electrical Circuits: Pole & Throw “Pole” indicates the number of circuits that oneswitchcan control for one operation of the switch. “Throw” indicates the number of contact points.NO and ...
Electricity stored in the traction battery pack is delivered to the electric motor. The motor converts this electrical energy into rotational mechanical energy. This mechanical power gets transferred to the wheels via the transmission/gearbox, propelling the EV forward. ...
National Electrical Code (NEC) is a set of regularly updated standards for the safe installation of electric wiring in the Americas. First published in 1897, the NEC is updated once every three years. The NEC provides guidelines for electrical installation to prevent fires and other electrical acc...
I personally don't think the higher pay would be worth it for working in a dangerous environment. A friend of mine is an electrician, and he eventually hopes to work his way up to the position of electrical superintendent. I hope he decides to stay away from oil rigs!
Electrical maintenance is the upkeep and preservation of equipment and systems that supply electricity to a building. The main...
The speed of the transmission of electrical current is very different to that of the speed of the actual electron movement. The electron itself bounces around in the conductor, and possibly only makes progress along the conductor at the rate of a few millimetres a second. This means that in ...
Electric charge is the basis for generating electric current. The electric current, described by the formulaI, is the directional movement or flow of electric charge. To generate electricity, you need two components: You need an electrical conductor that provides you with free charge carriers and ...
