I came to engineering by way of the technician route. I learned electronics in a technical school and was taught that current flow was electron flow and all circuit analysis was done that way.

Follow the current Remember that we call a collection of connected electrical or electronic components a “circuit” because currents always flow from a source to a load and then back via a return ...

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.

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 ...

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

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

Many introductory books on electricity try to relate voltage to water pressure, electric current to water flow, and resistance to changes in pipe volume.

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.
