Building simple circuits with copper tape, LED bulbs, resistors, and watch batteries is not as simple as you might think. Notre Dame Elementary School STEM students are putting the engineering design ...

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular Microchip ...

In modern industrial and household applications, single-phase motors are widely used due to their simple operation and low cost. However, effectively adjusting their speed is a common challenge. This ...

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, ...

[manuka], aka [Stan Swan] is a teacher in New Zealand who enjoys enlightening his students on the wonders of electrical circuits. He primarily uses “snap connector” circuit kits, sold under the ...

Over the last couple of decades the use of rechargeable batteries has grown enormously, and for most common applications there are ASICs[1] which control battery management with very little additional ...

Researchers have developed a wireless energy source that generates electricity from simple mechanical motion, such as the waves in the ocean, the tap of a foot or the clap of a hand. Researchers from ...
