Board-level designers often have concerns about the proper way to handle grounding for integrated circuits (ICs) which have separate analog and digital grounds. Should the two be completely separate ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals 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 ...

The multi-wire branch is here to stay; so is ground fault protection. But we should unite these technologies only when it’s a good match. Ground-fault protection and the multi-wire branch circuit ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

Understanding welding current and learning how a welding circuit interfaces with a building’s electrical system prevents horror stories from happening and leads to correct diagnosis when an incident ...
