CHOKE COIL IN TUBE LIGHTS… We saw in the last section that gases don’t conduct electricity in the same way as solids. One major difference between solids and gases is their electrical resistance (the opposition to flowing electricity). In a solid metal conductor such as a wire‚ resistance is a constant at any given temperature‚ controlled by the size of the conductor and the nature of the material. In a gas discharge‚ such as a fluorescent lamp‚ current causes resistance to decrease. This is

century alternator made inBudapest‚ Hungary‚ in the power generating hall of a hydroelectric station In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit. The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling through a turbine or waterwheel‚ aninternal combustion engine‚ a wind turbine‚ a hand crank

Theme : Electrical Sector and Chemical Engineer a) “The Chemical Engineer – His Role in Electrical Manufacturing” by N.R. Maleady The article is about the role of chemical engineer in manufacturing transformers in the electrical manufacturing sector. The important components of the transformer are copper wire‚ cellulosic insulation‚ insulating varnish and dielectric liquid. Wire enamel or resin is the insulting structure for copper wire. The resin can either applied as a solution or in solventless

These compounds are formulated as coatings‚ sealants and electrical encapsulants. The proper choice of PQD and a co-curative‚ such as lead dioxide or tertiary-butyl perbenzoate‚ will effect room temperature curing. PQD also functions as a curative for Ethylene Propylene Terpolymers (EPDM). Improved heat aging properties

Ward-Leonard Motor Generation System Introduction: A control system generally controls‚ regulates‚ and updates its output continuously based on present inputs‚ nature of the system‚ and the past outputs. In other words‚ there is a feedback mechanism that is inherent in the system‚ and is called a closed loop control system. For example‚ adding an emitter resistance to a common emitter amplifier‚ results in a negative feedback mechanism in the amplifier system – if the output current increases
