Without transistors the modern world would simply not exist. But how do they work, and how do modern, atomic sized versions compare with the originals? The word "transitor" has become almost invisible ...

Transistors are a type of semiconductor device that regulates the flow of electric current and voltage. From amplifying sound signals to enabling wireless communication, they are essential components ...

Researchers in Silicon Valley have managed to observe electrical switching that is thousands of times faster than transistors used in today’s computer chips. Their work could lead to a better ...

Deboki Chakravarti: You’ve probably seen pictures of those old computers. Not like the bulky ones that Sam and I used when we were younger. I’m talking about computers like the Electrical Numerical ...

Last month we showed you how to use resistors to reduce voltage. While it's a viable solution for many cases it isn't for others. As noted before, resistors work for devices whose load remains ...
