Normally, semiconductors don't have many free electrons. Since electric current relies on those free electrons, the amount of current that can travel through an isolated semiconductor is negligible.

This video explains what transistors are and how they function as electronic switches and amplifiers. As a core component of modern electronics, transistors control the flow of current and enable ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

Small electronic components "A transistor"Hundreds of millions of people are used in smartphones and PCs, which are indispensable to many people, as well as running a train, shedding music from ...

I was digging around in the LM311 (and LM111, LM211) comparator data sheet, and came across this unusual voltage reference (diag right). It consists of an npn cascsode pair of transistors, the top one ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of current and enable signal processing in everything from small devices to ...
