During the last two decades, we have witnessed great progress in research on thermoelectrics. There are two primary focuses. One is the fundamental understanding of electrical and thermal transport, ...

The rules of the National Electrical Code are written for people who have a pre-existing knowledge of electricity. In order to make sense of the Code, you must first understand basic electrical ...

THE partial success which has attended the recent attempts of Einstein and Minkowski to found an electromagnetic system of mechanics has tended to strengthen the popular idea that the solution of ...

It is critical for technicians to have a solid understanding of electrical fundamentals. This foundation enables them to develop a systematic and methodical approach to troubleshooting, which will ...

As we said last month, electrical theory underlies everything we do in the electrical construction business. It is therefore necessary to review this theory regularly. We continue now with Ohm's Law.

In last week’s Energy 101 column, we took a look at the basics of where our energy comes from now. This week, we’re examining the future of energy—specifically, the smart grid. To recap, a smart grid ...

Last week we looked at the smart grid — essentially, a modernization of the transmission and distribution aspects of the electrical grid. This week we’re focusing upon tracking energy usage, since the ...
