The damn thing worked – it showed the schematic symbol for an NPN transistor with Collector, Base, and Emitter connected to Pins 1,2,and 3 respectively.

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor.

The MIT research team used this new ferroelectric material in a transistor that could serve as the backbone of our digital world a decade from now.

For example, the number of atoms that tunnel from the source to the drain is extremely sensitive to the number of atoms in the gate, meaning atomic transistors could make more effective amplifiers.
