2Electrical conduction — is the movement of electrically charged particles through a transmission medium (electrical conductor). The movement of charge constitutes an electric current. The charge transport may result as a response to an electric field, or as a result of… …
3Electrical resistance — is a ratio of the degree to which an object opposes an electric current through it, measured in Ohms. Its reciprocal quantity is electrical conductance measured in Siemens. Assuming a uniform current density, an object s electrical resistance is… …
4Energy engineering — is a broad field of engineering dealing with energy efficiency, energy services, facility management, plant engineering, environmental compliance and alternative energy technologies. Energy engineering projects often combine expertise from civil …
5Energy density — For energy density in the sense of energy per unit mass, see specific energy. For energy density of foods, see specific energy. Energy density is a term used for the amount of energy stored in a given system or region of space per unit volume.… …
6Electrical machine — is a device that convert either mechanical energy to electrical energy or vice versa, and change AC voltage from one level to another level.Electrical machines are divided into three parts:GeneratorGenerator is the device that converts mechanical …
7Electrical engineering — Electrical engineering, sometimes referred to as electrical and electronic engineering, is a field of engineering that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable… …
8Energy harvesting — (also known as Power harvesting or energy scavenging ) is the process by which energy is captured and stored. Frequently this term is applied when speaking about small autonomous devices, like those used in sensor networks. A variety of different …
9Electrical resonance — occurs in an electric circuit at a particular resonance frequency when the impedance between the input and output of the circuit is at a minimum (or when the transfer function is at a maximum). Often this happens when the impedance between the… …
10electrical potential — or electric potential n the potential energy of a unit positive charge at a point in an electric field that is reckoned as the work which would be required to move the charge to its location in the electric field from an arbitrary point having… …
