Fundamental electrical engineering concepts and theory
Resistors are electronic components that oppose the flow of current. Manufactured in various types and ranges they have a wide application to electronics...
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
"I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong...
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
The term 'N+1' relates to redundancy and simply means that if you required 'N' items of equipment for something to work, you would have one additional...
Variable frequency drives are widely used to control the speed of ac motors. This note looks at the mechanisms which enable drive units to control the...
If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...
