have ever been created. Very few people really knows how they work. The simplest computer described consists mainly of a processor and main memory. Though most explanation of how computers work are a lot of analogies or required a background in electrical engineering. In this book we are going to describe the development of computer. The earlier computers are very big in size. Even its operation is not possible for one person. History of Computer Even before humans

synchronous machine can operate as both motor and generator. They are used primarily as electrical power generators. They are usually large machines generating electrical power at hydro, nuclear or thermal power stations. Synchronous generators with power rating of several hundred MVAs are quite common in generating stations. Synchronous generators are the primary energy conversion devices of the world’s electrical power systems today. Because the rotor speed is proportional to the frequency of excitation

to be studied is designed and simulated using the software, CYME 5.02 Power System Simulation Software. The system chosen for the study is that of a two machines system, involving two synchronous generators connected to a substation grid through circuit transmission lines. In order to gain much further comparison of the results, it is considered also the two different types of synchronous generators’ rotor types, salient-pole rotor and non-salient pole (round) type rotor. Transient stability studies

are driven by prime movers, transformers, bus bars, circuit breakers, power stations ,and other auxiliary devices that are used to transfer power from source to load in most reliable economical and efficient manner. An electric power system is a network of electrical components deployed to supply, transfer, store, and use electric power. An example of an electric power system is the grid that provides power to an extended area. An electrical grid power system can be broadly divided into the

------------------------------------------------- Microwave an RF Supplementary Project ------------------------------------------------- Equivalent Impedance of an Antenna Introduction: Antenna impedance is a measure of the resistance to an electrical signal in an antenna. Many factors have an impact on an antenna’s ability to transmit a signal, including the environment that the antenna is in and the design and composition of the antenna. Understanding antenna impedance is important when designing

ordering, tracking, manufacturing, and delivering of our high voltage transformers. This is a very important part of our company because these machines are of high cost and a vital part of the electrical engineering process. A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors. It is used to “step up” and “step down” the voltage of electricity as it moves between lines, substations, plants and buildings. These transformers

been around because it naturally exists in the world. Lightning, for instance, is simply a flow of electrons between the ground and the clouds. When you touch something and get a shock, that is really static electricity moving toward you.Hence, electrical equipment like motors, light bulbs, and batteries aren't needed for electricity to exist. They are just creative inventions designed to harness and use electricity.The first discoveries of electricity were made back in ancient Greece. Greek philosophers
