Fundamental electrical engineering concepts and theory
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
For the past few years I have reading eBooks on my HTC touch phone. On and off I have debated buying an eReader and recently purchased a Sony PRS-300 ...
Electrical engineering has a multitude of laws and theorems. It is fair to say the Ohm's Law is one of the more widely known; it not the most known. Developed...
Motor starting and its associated problems are well-known to many people who have worked on large industrial processes. However, these things are, of course...
Our IEE cable sizing was wrote a few years ago and had become rough around the edges. I thought it was time to give the tool a service. Unfortunately when...
The other day I came across an article in Technology Review on the development of a smart transformer. A professor at North Carolina State University is...
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
Before the technical, some general information. E-ink display are found in a lot of e-readers, some mobile phones and similar devices and the intent is...
Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr)...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
