Atransistorworks by controlling the flow of current through a semiconductor material. The current is controlled by the voltage applied to the transistor’s base.Transistorscan be used as switches or amplifiers. When used as a switch, the transistor can be turned on or off, depending on the vol...

The emitter, base and collector have the same functions in a PNP circuit. The only difference in the PNP transistor is that the n-type base is layered between the p-type emitter and collector. The NPN versus PNP configurations determine the direction of the emitter's arrow, which is always...
This is the amplification effect of a transistor. The base-emitter junction can also act as a switch. When no current is applied to the base, the junction prevents current from flowing from the emitter to the collector, and when a current is applied to the base, it allows the current to...
Semiconducting two-dimensional materials might one day be used in scaled semiconductor technology. Andras Kis recounts how the first transistor based on a single layer of molybdenum disulfide was created.doi:10.1038/s41928-021-00675-wAndras KisSpringer NatureNature Electronics...
The transistor is one of the basic semiconductor components, which has the function of current amplification and is the core component of the electronic circuit. The transistor is made of two PN junctions very close to each other on a semiconductor substrate. The two PN junctions divide the whol...
This type of transistor is made from semiconductors. Transistors are used in the construction of Integrated Circuits (ICs). The number of transistors that we have been able to fit into an IC has rapidly increased since their creation, doubling approximately every 2 years (known as Moores Law)....
If we crank up the Base Battery voltage, the emitter's depletion layer thins, the "switch" is fully on, and a very large flow of charge might appear in the collector circuit. Uh oh. The transistor (as a switch) is trying to short out the collector battery. So lets have it switch ...
Check out the video explanation I made on the transistor a few years back (forgive the old-school quality): How To Choose a Transistor The NPN transistor is the most common of theBipolar Junction Transistors (BJT). But there is another one called aPNP transistorthat works the same way, ju...
A transistor is a switch with two positions: on and off. If you go back to the early days of computing, that was all a computer needed to get the job done. The machine has two options: on and off, which are 0 and 1. So, how would you go about making a CPU? In today's ...
