Basic definition

-


 1.Circuit :

"Combination of various element or parameter(e.g resistance, inductance, Capacitance) to form conducting path where current flow.

2.Charge :

 They are 2 types of charge, positive and negative charge. Proton are positive charge and Electron are negative charge. The unit of charge is Coulomb, denoted by "C". 1 charge=1.601x10-19 Coulomb.

3.Current :

"Flow of charge(i.e proton, electrons ) within conducting medium.

Introduction :                                  Silicon Control Rectifier is electronic semi-conductor device. Its also known as current controlled device. The name "silicon controlled rectifier" is  general electric"s trade name for type of thyristor. The SCR was invented by  Gordon Hall and Frank W. "Bill" Gutzwiller in 1957. SCR is unidirectional device so that it conduct current only in one direction. Construction :  Silicon Control Rectifier (SCR) is three terminal device(Anode, Cathode, Gate),which consists four layers of semi-conductor, which form NPNP or PNPN structure having  three P-N junction terminal i.e J1, J2, J3. Anode (A) terminal is connected to p-layer, and Cathode(K) terminal is connected to n-layer  and Gate(G) terminal is connected to p-layer nearest to cathode.

 Exhaust fans is electrically operated device. When supply given to exhaust fan, blades of fan are rotates.  Once blades are rotate,it absorb the hot air in the room where exhaust fan fitted and released outside the room. Design of Blades : Exhaust fan blade placed in cross type to inner sides. Fig-Blades view Exhaust fans are used in household as well as industry. In the industry exhaust fan used in cooling tower to absorb the hot steam in the water. Working of exhaust fan :

Cables are used to supply electricity. Cable are used in every motor connection,controlling panel etc etc. There are different types of cables are PVC(Polyvinyl chloride) Cable,Semi Rigid-PVC, Plenum polyvinyl chloride,polyethylene,nylen etc Cable are also manufacture by current and voltage ratings Cables are available in single core,3 core, 4 core multi-core  Process for production of cables :  Bunching the copper wire as per size.Bunching increases current carrying capacity of wires. After  bunching wire is pass from nozzle, it check proper size. Polyvinyl chloride is heated as per color  required. Heated wire passed from water shower for cooling purpose. Spark test Coiling the cables Packaging cables Construction :
