This pressure difference causes water to flow around the loop – just like the potential difference produced by a cell or battery causes electrical current to flow in a circuit.

A printed circuit board turns separate parts into a stable system that powers up, talks to peripherals, and survives real ...

The short circuit case is easy to detect with an electromagnet that will have a strong magnetic field when so much current flows. However, the overload case isn’t that abrupt.

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by ...

Conventional current takes just the opposite direction, from the positive terminal, around the circuit and back to the negative terminal.

A VRM is an essential part of every computer, but even many computer-savvy enthusiasts don't know what it is or how it works. We'll explain all.

Most common current-limiting implementations have a voltage drop that’s too high for today's systems with their low-voltage supply rails; this design with its far lower voltage ...
