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 ...

In the Feb. 22 issue of RWEE, we asked: What is skin effect in alternating current and what is its relationship to current flow? a. Skin effect is the tendency of all current flow on printed circuit ...

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 ...

The film explains how electric current is generated at power plants and delivered to homes through wires. It describes the concept of electric circuits, including closed and open circuits, and the ...

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 . . .

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

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 ...
