Solid Dielectrics Used in Practice: The majority of the insulating systems used in practice are solids. They can be broadly classified into three groups: organic materials, inorganic materials and synthetic polymers. Some of Solid Dielectrics…
Solid Dielectric Materials and Composites Materials: A good solid dielectric should have some of the properties mentioned earlier for gases and liquids and it should also possess good mechanical and bonding strengths. Many organic and…
Solid Dielectric Materials: Solid dielectric materials are used in all kinds of electrical apparatus and devices to insulate one'current carrying part from another when they operate at different voltages, A good dielectric should have low…
Solar Powered Pump Drives: Solar Powered Pump Drives: Centrifugal and reciprocating. Their speed-torque characteristics are shown in Fig. 9.3. Centrifugal pump requires only a small torque to start whereas reciprocating pump owing to stiction may…
Solar Panels or Photovoltaic Cells: A Solar Panels or Photovoltaic Cells converts sunlight into electricity. Single crystal, polycrystal and amorphous silicon cells have been employed. The open circuit voltage is about 0.5 V for mono-and…
Solar Energy Conversion Diagram: The Solar Energy Conversion Diagram, or solar energy converter, is essentially a large photodiode designed to operate solely as a photovoltaic device and to give as much output power as possible.…
Sodium Vapour Lamp - Construction, Working and Wiring Diagram: Principally the sodium vapour discharge lamp consists of a bulb containing a small amount of metallic sodium, neon gas, and two sets of electrodes connected to…
Smoothing Circuits: The rectified a.c. consists of a series of undirectional half waves of current or voltage. It is generally desirable to smooth this output. The various filters used for Smoothing Circuits are the conventional…
Smith Chart for Transmission Line: The various properties of transmission lines may be represented graphically on any of a large number of charts. The most useful representations are those that give the impedance relations along…
Small Signal Model of MOSFET: If the small bulk resistances of the source and drain are neglected, the Small Signal Model of MOSFET and its equivalent circuit between terminals G (G1), S, and D is…
