Fundamental electrical engineering concepts and theory
I was reminded of Occam's Razor while reading a book. It's quite a simple principal of logic which has stood the test of time and is accepted as central...
Control theory looks at how systems work and are controlled from a mathematical view. This note gives a brief introduction to some of the concepts – more...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
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...
Dielectrics (insulating materials for example) when subjected to a varying electric field, will have some energy loss. The varying electric field causes...
If you have no idea how electrical circuits work, or what people mean then they talk about volts and amps, hopefully I can shed a bit light. I’m intending...
This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...
It starts with me reading one of the Horrible History books with my son (Groovy Greeks). Arrows were mentioned which lead to the discussion of the bodkin...
Capacitors have numerous applications in electrical and electronic applications. This note examines the use of capacitors to store electrical energy....
