Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Circuit breakers are used in nearly all electrical systems — from residential dwellings to electric utility facilities. We rely on them to protect our systems from damaging overcurrents and short ...

MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable ...

They do not depend on temperature as a tripping mechanism, so they often find use where ambient temperatures are high. Their insensitivity to temperature also makes them candidates for protecting ...

If you think shorting a transformer’s winding means big sparks and fried wires: think again. In this educational video, titled The Magnetic Bypass, [Sam Ben-Yaakov] flips this assumption. By cleverly ...

Your circuit breakers are some of the most important but least understood parts of your home's electrical system, keeping you safe from electrical fires. Let's take a look at how they work.

MIT researchers developed a more powerful magnetic transistor that could be used to design simpler circuits and create faster and more energy-efficient electronics.
