Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

This video explains what a diode is and how it controls the direction of current in electronic circuits. Diodes allow current to flow in only one direction, making them essential for rectification, ...

Diodes today are solid-state devices, but in the beginning of the electronics age, they were crystals, as it was the German physicist Ferdinand Braun who first discovered in 1874 that crystals had ...

I'm sort of curious myself. I've been on the software side of things for a long time, but I have a lot of EE coworkers, and I've been curious about learning a little about building electronics, to the ...

I learned some basic electronics in high school physics class: resistors, capacitors, Kirchhoff’s law and such, and added only what was required for projects as I did them. Then around 15 years ago I ...

Read the article to find out how commonly lasers are used in different applications. Laser technology is commonly used in a wide range of industrial and medical equipment, but also in devices found in ...

Researchers have found a way to make a key electronic component on a phenomenally tiny scale -- a single-molecule diode. Recently, at Arizona State University's Biodesign Institute, N.J. Tao and ...
