These are analogous to the terminals on a bipolar transistor, in that the source fulfills a similar role to the emitter, the gate to the base, and the drain to the collector. Thus the three basic ...

The transistor acts like an insulator or a switch that is turned off. When a positive voltage is applied to the base, electrons are pulled out of the junctions and they no longer act as barriers.

Electricity can race through. The transistor base (the "meat" of the sandwich) acts like the handle on a faucet. Turn it one way and current will gush through like water through a hose.

Instead of connecting the transistor base to power, we will connect it to one of the mini-D1 output pins (we chose D0). In this case, the firmware causes the ESP8266 to raise pin D0 high when it ...

A landmark development led by researchers from the University of Glasgow could help create a new generation of diamond-based ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the ...
