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 – ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

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 ...

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 \(0.7 V\).

A new material can withstand 'billions' of electrical cycles without wearing out — and scientists say it could transform electronics within 10 to 20 years. When you purchase through links on our site, ...

Physicists have managed to control the rotation of light by means of a ultra thin semiconductor. The advance could potentially be used to create a transistor that works with light instead of ...
