This video explains how transistors work and how they are used to switch and amplify electrical signals in electronic ...

The use of transistors for switching things ON and OFF is a key feature of proper hacking. The ability for bipolar transistors to turn things ON and OFF is one of the less known uses while transistors ...

The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...

Have you ever heard of topological insulators? These are exotic materials where electricity flows only on the surface with very little loss. Now, according to IEEE Spectrum, scientists at Harvard have ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

To meet the growing demands of flexible and wearable electronic systems, such as smart watches and biomedical sensors, ...

Thermocouples and their leads often have to detect open-circuit or short-circuit faults. However, it is very difficult to distinguish a valid millivolt temperature signal from an open/short-circuited ...
