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 . . .

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 ...

This video explains how transistors work and how they are used to switch and amplify electrical signals in electronic circuits. Transistors are fundamental to all modern digital and analog systems.

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 ...

How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material. Most transistors have three terminals, often ...

IT is well known that changes in the d.c. characteristics of transistor amplifiers with temperature are particularly severe, and tend to limit the range over which these devices can operate. The d.c.
