LANLocal Space Community, an interconnection of computers over a building or small campus. Laplace transformA mathematical operation for answer of differential equations by remodeling them to the s area from the time area. Laser diodeA semiconductor device that produces coherent laser radiation when correctly energized. Leakage inductanceThe inductance of a transformer that outcomes from magnetic flux not linked by each main and secondary windings. Gentle-emitting diodeA semiconductor system that produces light or infrared or ultraviolet radiation when correctly energized. Linear alternatorAn electrical machine that generates electric energy from the relative straight line motion of its elements. Linear motorAn electrical machine that generates electric power in a straight line by the interplay of its transferring components and superuser.com
magnetic fields. Linear variable differential transformerA transducer that produces an electrcial sign proportional to the motion between its elements. Lineman (occupation)A specialist technician who installs outdoors plant wiring (overhead circuits, power transmission traces). Litz wireA form of stranded wire used to minimize losses in coils. Load flow studyA mathematical prediction of the circulate of electric power in a community, based mostly on a model of the actual or proposed system; obligatory for planning of electrical grids. Load following energy plantA power plant that can economically be operated over a big vary of output, so as to meet various electric power demand. Load-loss factorA issue for estimating power lost in a distribution network because of load present. Load managementAny technique for altering the operation of buyer loads so as to scale back peak demand on an electrical grid. Load profileThe each day, weekly or annual plot of electrical load in opposition to time. Native positioning systemA navigation system that does not cover the whole Earth; comparable to over a coninent, or even inside a building. Lorentz pressure lawThe mathematical relation between currents in conductors and the resulting magnetic forces between them. Lossless data compressionAny knowledge compression method the place the supply will be reconstructed precisely; the place approximations are tolerable, lossy knowledge compression can be used. Lossy data compressionAny data compression method which allows only a close approximation of the supply to be reconstructed; useful for images or music, the place the human perceptual system compensates for the errors. LoudspeakerA transducer that converts electrical current into sound, perceptible to a couple of listener. Low-noise amplifierIn a satellite radio receiving system, an amplifier placed near the antenna. Low-noise block downconverterIn a satellite radio receiving system, a system that amplifes and converts signlas to a lower frequency band that can have decrease losses in interconnecting cables. Low-move filterAn electric filter community that passes lower frequencies and blocks greater ones. LTI system theoryThe concept of systems that, over a useful range, respond proportionally to inputs and don't change characteristics whereas responding. Lumen (unit)The SI unit of luminous flux, the power of seen mild. Lumped parametersDescribes an electrical network where the circuit components are small in comparison with the wavelengths of the signals passing by way of it. Lyapunov stabilityA criterion for stability of a dynamical system; if disturbances from a stable level scale back and the system returns to that stable point, it can be mentioned to be Lyapunov stable.
