Electrical telegraph

has about 2332 patents worldwide proving he was really a great inventor. However, what proved his amazing skilling creating/designing are the useful products that are used throughout society till date. Edison’s inventions/designs such as the first electrical power grid, the light bulb, the alkaline battery and the world’s first movie camera, really made a huge impact on today’s modern society, changing major aspects of everyday life. One of Edison’s most famous inventions till date is the light…

The Career Fair: Computer Software Engineer Career Description Computer software engineers are the main reason that computers are so popular these days. Everything you do on a computer from just typing up a research report, to video chatting and playing games is achievable because of computer software, which is created by computer software engineers. Computer software engineers are responsible for designing and developing software applications and software that are used everyday. The two…

But what does the real world look like? This question is so ambiguous that it has become a canned question that stumps some interviewers. Based on my three internship experiences (though diverse across location and industry), a more realistic answer of what a software engineer does instead of just reading a spec and working with teammates from a solid 9-5 (or 10-6) is this. The engineer gets in the office, opens Outlook, and proceeds to get inundated by emails sent while he was eating dinner or…

Chapter: 1 INTRODUCTION Basic theory of power transfer network We know that AC lines are operated at voltage level between 10kv to 800kv. The distribution network operates voltage level below the 100kv. For protection against fault circuit breakers are used. Power flow is obtained by receiving end power or sending end power. Ex. Consider a transmission line connected between load centre and generating station. We assume line is loss less and ignore line charging, then the power flow (P)…

closely associated with the field of Electrical and Electronics. Right from my school days I was inevitably enthralled by the functions of electrical and electronics equipment. By the time I was preparing for my 12th board practical examination I had quite figured out what I wanted to be or which one I would choose for something that would make me quite curious and also amaze me to a great extent that I wanted to learn more. Engineering was my choice and electrical in particular. The reason…

Chapter 3 Interleaved Buck Converter System 3.1 INTRODUCTION Interleaved Buck Converter has lots of concentration due to its simple and low control complexity in application. where no isolation and high output current with low ripple. An No isolation DC/DC converter Fig.1.1 shows the step-down DC/DC converter. When switch M is on for the duration of dTs, power is transferred from source to load and filter inductor L is charged. When switch M is off for a duration (1-d)Ts, the diode D…

Rotor and touchdown bearing models Fig. 1 features the case study of the high-speed rotor. The photo was taken after manufacturing of the electric motor part, when the rotor was carried to the laboratory for an experimental modal analysis. During normal operation, the rotor is supported by AMBs. In the dropdown event, the rotor is in contact with touchdown bearings at both ends of the rotor. Fig. 1. Rotor under investigation. In this work, the finite element model of the rotor employs…

Do you like to help people? Well, if you do this is exactly what biomedical engineers do. Biomedical engineering is the career I chose. I want to be a biomedical engineer because this career involves math and science. I am good at math and I really like most of the topics in science, including biology. I am proving that biomedical engineering is a great job by showing the work environment, the education and training required, the important qualities needed, the salary, and the job outlook. Work…

I felt deeply identified with Neil Gaiman's approach to reading and daydreaming, since I really felt it cleared my mind, relating daydreaming to reading. I never thought about this relationship until today. I consider his article was very touching, since he uses his own experience and memories to illustrate his idea, which I find quite accurate, not only because I have read and discussed about this before, but also because I just felt it was true. Since I was a child, I was aware that…

When it comes to electrical issues, you never want to wait to get them fixed. Even if an electrical issue seems harmless on the surface, by letting the issue go unfixed you are actually putting you and your family at risk (and possibly other people if the issue results in an electrical fire that spreads). But, what exactly constitutes an electrical emergency? Realistically, you should always get an electrical issue looked at ASAP no matter how small, but there are certain electrical issues that,…
