These study materials are designed for undergraduate students of electrical engineering and computing to complement the coursebook that is studied in class. We try to supply students with additional texts and exercises believing that a larger language, especially lexical, input can be nothing but useful for their further education.

Electric motors provide the driving power for a large and still increasing part of our modern industrial economy. The range of sizes and types of motors is large and the number and diversity of applications continues to expand. The computer on which this book is typed, for example, has several electric motors inside, in the cooling fan and in the disk drives. There is even a little motor that is used to eject the removable disk from its drive. All around us there are electrical devices that move things around. Just about everything in one’s life that whine, whirrs or...

semiconductors.In the first category are substances which provide an easy path for an electric current. All metals are conductors, however some metals do not conduct well. Manganin, for example, is a poor conductor. Copper is a good conductor, therefore it is widely used for cables. A non-metal which conducts well is carbon. Salt water is an example of a liquid conductor. A material which does not easily release electrons is called an insulator. Rubber, nylon, porcelain and air are all insulator. There are no perfect insulators.

In industrialized countries, distribution systems deliver electricity literally everywhere, taking power generated at many locations and delivering it to end users. Generation, transmission, and distribution — of these big three components of the electricity infrastructure, the distribution system gets the least attention. Yet, it is often the most critical component in terms of its effect on reliability and quality of service, cost of electricity, and aesthetic (mainly visual) impacts on society....

Engineering for sustainability is an emerging theme for the twenty-first century, and the need for more environmentally benign electric power systems is a critical part of this new thrust. Renewable energy systems that take advantage of energy sources that won’t diminish over time and are independent of fluctuations in price and availability are playing an ever-increasing role in modern power systems.

Electricity is an invisible force that is used to transfer energy into heat, light, intelligence, or motion. Electricity is explained in terms of electrical charge, potential differ- ence (or voltage), electrical charge flow (or current), and resistance to current flow. Figure 1-1 graphically illus- trates electron flow through a conductor by comparing it with water flow through a pipe. The normal unit of current measurement is the ampere, whereas the normal unit of voltage measurement is the volt. The unit of opposition to current flow, or resistance, is the ohm...
