The speed of a dc shunt motor is directly proportional to the back emf and inversely proportional to the flux per pole. DC shunt motors are very useful and important part of any motor application. The motor speed control in dc shunt motor is very crucial because it impacts the use and design of the… Read More »
This page is dedicated for providing best and up to date information about the coulomb’s law. In addition you can find the definition, equation and formula for understanding the basic concept of coulomb’s law. You already know that when two charged bodies come closer there is always a force of attraction or force of repulsion. What is… Read More »
Conductivity refers to the ability to conduct, convey or pass through, and in case of electricity it refers to ability to convey the electric current. On the other hand for thermal conductivity it is the ability to conduct or pass the heat for any material. Similarly if we talk about the reverse side of conductivity… Read More »

Optical fiber cable is the most important subject for large data and voice communication. Obviously like all other communication system, the primary objective of optical fiber communication system is to transfer successfully the signal containing information (voice, data, video) from the source to the destination without any or minimal data losses. Since the signals in… Read More »
Fiber Optic cable is made up of thin fibers which are useful for the transmission of large amount of data. Infact the optical fiber is a hair thin cylindrical fiber of glass or any transparent dielectric medium. The fiber which are used for optical communication are wave guides made of transparent dielectrics. Its function is… Read More »
