I have talked about the course I teach for elementary education majors before (videos for education majors, Spring Course reflections). Anyway, the nature of the course is that students collect ...

Inside nearly every electronic device is a simple coil of wire doing a powerful job—it’s called an inductor. Though small and ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

Explains electric current, highlighting that it originates from a battery and requires a complete circuit to flow. It compares electric current to water flowing through pipes, using meters to ...

Do you want to build an electric motor? You could probably find just about everything you need for a simple one around your house. Let me show you how to build it and why it works. Start With Magnet ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

Researchers have developed a way to assess soil health by measuring the electric current produced by its tiniest microbes. They used a probe originally developed to measure the electrochemical signal ...

The size of a capacitor affects how much charge it can store (its capacitance), its voltage rating, and its physical ...
