This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

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 ...

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 ...

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 ...

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

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 ...
