On a physical level, a transistor’s internal functioning is very complex, but, in practice, using it in some simple experiments is quite easy and affordable for everyone. A transistor allows to create ...

Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of current and enable signal processing in everything from small devices to ...

Process devices operate when an input level, such as voltage, reaches the required value for the device to operate. The transistor is on, when the input voltage is greater than or equal to \(0.7 V\).

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 ...

The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and ...

Back in 1966, a suitable toy for a geeky kid was a radio kit. You could find simple crystal radio sets or some more advanced ones. But some lucky kids got the Philips Electronic Engineer EE8 Kit on ...
