In this lesson, students search for transistor-based devices at school. They use the results of their search to explain the significance of the transistor in their lives. A transistor is a tiny device ...

The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...

The telephone company had problems with vacuum tubes, too, and hoped to find something else to use for switching telephone calls. The idea of somehow using semiconductors (solid materials such as ...

The late 1950s and early 1960s saw perhaps the most dramatic change ever to hit electrical engineering. When transistors came along, many engineers needed to quickly learn how they worked and how to ...

For the first time, scientists have built a transistor out of carbon nanotubes that can run almost twice as fast as its silicon counterparts. This is big, because for decades, scientists have been ...

“The first digital use of the transistor for consumers was in a calculator,” says Rick Bensene, curator of the Old Calculator Web Museum. Our series on the birth of the transistor — and with it, the ...

A reconfigurable transistor can run AI processes using 100 times less electricity than the standard transistors found in silicon-based chips. It could help spur development of a new generation of ...

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 ...
