This video explains how inductors work and how they store energy in a magnetic field when electrical current flows through them. Inductors are passive components used to resist sudden changes in ...

Ballistic electrons are among the most fascinating phenomena in modern quantum materials. Unlike ordinary electrons, they do ...

Scientists are facing a number of barriers as they try to develop circuits that are microscopic in size, including how to reliably control the current that flows through a circuit that is the width of ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

Using a current limiter in boost converters for circuit protection. An easy-to-implement design idea to achieve the desired current limiting. 1. A current limiter is added to a power bank that has an ...

In order to test and characterize optical front end circuits, a controllable, high bandwidth, microamp-level current source is needed. However, most optocouplers on the market have large CTR variation ...

Beyond simple on/off use cases, you’ll find linear solenoids in many applications requiring precise linear motion and the regulation of pressure, fluid or air. Automotive applications include ...
