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 . . .

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of ...

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 ...

A transistor is a tiny but powerful electronic component that acts like a switch or an amplifier. It is made from a semiconductor material, usually silicon, and has three legs for connection to ...

Transistors are an indispensable building block in electric appliances, where they amplify weak electric currents. Now researchers have developed a new type of transistor that is 50 times more energy ...
