INTRODUCTION: Electric circuit theory and electromagnetic theory are the two fundamental theories upon which all branches of electrical engineering are built. Many branches of electrical engineering, such as power, electric machines, control, electronics, communications, and instrumentations, are based on electric circuit theory. Therefore, the basic electric circuit theory is the most important course for an… Read More »

Recently Energy and Environmental Research Group (EERG) of Mehran University of Engineering and Technology (MUET) has successfully organized its 3rd International conference on 22-24th of October 2014. General Information for 4th International Multi… Read More »
Introduction: Electrical engineering technology (EET) is an engineering technology that implements and applies the principles of electrical engineering. Like electrical engineering, EET deals with the “design, application, installation, manufacturing, operation and/or maintenance of electrical/electronic(s) systems.” However, EET as a discipline is generally more focused on application and implementation, while electrical engineering may place more of… Read More »
Historically there have been major shifts in the software industry. We moved from mainframes with dumb terminals to client/server. Users gained in convenience and productivity, and mainframe systems were patronizingly labeled as legacy. With the availability of the World Wide Web industry, visionaries turned the tables; vendors and corporate IT had been eager to get rid of the… Read More »
Radio Frequency Electronics This second, much updated edition of the best-selling Radio-Frequency Electronics introduces the basic concepts and key circuits of radio-frequency systems. It covers the fundamental principles applying to all radio devices, from wireless single-chip data transceivers to high-power broadcast transmitters.
The d.c. generators and d.c. motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a d.c. generator or motor. Any d.c. generator can be run as a d.c. motor and vice-versa. All d.c. machines have five principal components viz., (i) field… Read More »
Generator Principle An electric generator is a machine that converts mechanical energy into electrical energy. An electric generator is based on the principle that whenever flux is cut by a conductor, an e.m.f. is induced which will cause a current to flow if the conductor circuit is closed. The direction of induced e.m.f. (and hence… Read More »
