There are temples and other sacred places all along this stretch. At about 200 meters from the gate "UPARKOT" (Girnar Darwaza), to the right of the road, is temple of wagheshwari, which is joined to...

ELECTROSTATICS & CAPACITORS

ELECTROSTATICS & CAPACITORS ELECTRIC CHARGE • Amount of current flowing in a conductor is measured in electric charge. • Two different kinds of charge, positive and negative. • It’s denoted by Q or q. • Electric charge is measured in Columb (c). LAWS OF ELECTROSTATICS • The space around a charge is always under stress, and experiences a force on another charge when placed there. • The region or space in which stress exists is called the electric or dielectric or electrostatic field. • The stress in the space is represented by the line of force. PERMITTIVITY • Permittivity of free space. • The permittivity of free space is a physical constant used often in electromagnetism. • It represents the capability of a vacuum to permit electric fields. • It is also connected to the energy stored within an electric field and capacitance. ELECTRIC FIELD • It is found that in the medium around a charge a force acts on a positive...

Hydro Power Plant

HYDRO POWER PLANT A generating station which utilizes the potential energy of water at a high level for the generation of electrical energy is known as a “Hydroelectric power station”. 1) selection of site: ➢ Sufficient quantity of water at a reasonable head should be available. ➢ More area is required for reservoir and dam. ➢ It should allow strong foundation with low cost. ➢ There should be no leakage of water in future. ➢ Selected site should have large catchment area, to maintain a certain water level. ➢ Distance of power station site from load centre must not be longer. This is to minimize the transmission cost. ➢ Construction material shall be available very near. ➢ Submergency area should be minimum. 2) Schematic arrangement of Hydroelectric power station. (1) Hydraulic structure : (a) water reservoir : It’s purpose is to store water which may be utilized to run the prime mover to produce electrical power. (b) Dam : The function of dam is to prov...
