In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...

Properly selected components make it easier to design modern, energy-efficient power supplies. In this article we present an ...

Power management is generally accomplished by a combination of small signal transistors acting as the brain, power transistors acting as solid state switches that control the power flow from the ...
