Ever since my childhood, the drill of using a manual toothbrush is ingrained in my brain. Move the brush back and forth along the gums, clean the outer surfaces of the teeth, move to the inner ...

Imagine learning to operate a piece of machinery you've never previously touched, not through a tutorial, but through your own hands electrically guided through the right motions. That's the core idea ...

In part 3 of this series, we used Kirchhoff’s voltage law to derive the branch currents and node voltages for an unbalanced ...

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, ...

Discover how to create a simple electric motor using everyday materials in this step-by-step tutorial. Learn how to build a homemade DC motor by winding copper wire into coils, constructing a custom ...

It’s one thing to learn about transmission lines in theory, and quite another to watch a voltage pulse bounce off an open connector. [Alpha Phoenix] bridges the gap between knowledge and ...

This video demonstrates how you can detect and draw a magnetic field using some iron filings, a compass and a magnet. You’ll notice that the arrows on your lines always point from the north to the ...

The topic of boiling water is apparently a rather divisive topic, with plenty of strong opinions to go around on what is safe ...

Caroline Igo (she/her/hers) was a wellness editor at CNET and holds Sleep Science Coach and Stress Management certificates from the Spencer Institute. She received her bachelor's degree in creative ...

Abstract: Low-noise current readout circuits are essential in modern scientific and industrial applications ranging from nanopore sensing to quantum systems. This tutorial-style paper presents a ...

Abstract: In this paper, to mitigate the risk of irreversible motor demagnetization during short-circuit faults, a demagnetization assessment and design optimization approach is proposed for the ...
