Introduction Stator Voltage Control of an Induction Motor is used generally for three purposes – (a) to control the speed of the motor (b) to control the starting and braking behaviour of the motor (c) to maintain optimum efficiency in the mo ...
Introduction It the process that takes place in any system where electrical energy is transmitted from a power source to an electrical load, without interconnecting wires. Wireless transmission is employed in cases where instantaneous or c ...
Introduction Don't you hate it when you forget to put your mobile phone on charge? Well, take heart - a new technology called WiTricity could mean never having to plug it in again. Welcome to the world of WiTricity . E ...
An electric motor converts electrical energy into mechanical energy. The reverse process that of converting mechanical energy into electrical energy is accomplished by a generator or dynamo. Traction motors used on locomotives often perform both tasks ...
Transformer is one of the most vital electrical machinery. The development of the present day power system is very much attributable to the large number and types of transformer that are in operation in the system, such as, generator transformers, step ...
Utilities include WA the tank and the cover are manufactured of hot-rolled, unalloyed steel sheet and profile balks. Fine granular steel is used in transformers for low ambient temperatures. Areas where strong eddy currents can be generated du ...
History The transformer principle was demonstrated in 1831 by Michael Faraday, although he used it only to demonstrate the principle of electromagnetic induction and did not foresee its practical uses. The first widely used transform ...
Almost any liquid or moist object that has enough ions to be electrically conductive can serve as the electrolyte for a cell. As a novelty or science demonstration, it is possible to insert two electrodes made of different metals into a lemon, potato e ...
By taking the equivalent circuit for an SCR and add another external terminal, connected to the base of the top transistor and the collector of the bottom transistor, we have a device known as a silicon-controlled-switch, or SCS: <IMG src="/img/0 ...
Introduction Both Hall and Heioult selected molten cryolite (Na3 AIF6) as the electrolyte for the electrolysis of alumina because cryolite has uniquely high solubility for oxides although certain additives are beneficial, the major component ...
