This course covers AC circuits under sinusoidal steady-state conditions using the concept of the frequency domain. Introduces the use of complex numbers, phasors, impedance and admittance for the ...

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 ...

When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true.

The aim of the course is to provide insights and understanding of complex static and dynamic behavior of circuits consisting or bipolar and MOS transistors. Topics will include: global properties of ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...
