Fundamental electrical engineering concepts and theory
I was having a conversation the other day about voltage levels. While everyone was in agreement that low voltage was 1000 V and less, there was more confusion...
The fundamental component of any analogue computer is the operational amplifier, or op amp. An operational amplifier (often called an op-amp,) is a high...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
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...
