A Bipolar Junction Transistor (BJT) is called "bipolar" because it uses both types of charge carriers—electrons and holes—for its operation. In an NPN transistor, electrons are the majority carriers in the n-type regions, while holes are the majority carriers in the p-type region. The interaction between these two types of carriers allows the BJT to amplify current. This dual carrier mechanism is what distinguishes BJTs from unipolar devices, like MOSFETs, which rely on only one type of charge carrier.

What are the example current controlled device?
Bipolar junction transistor(BJT)
What is bipolar ic?
ic made from bjt is known as bipolar ic
Why bjt is bipolar?
BJT stands for bipolar junction transistor because it is composed of two types of semiconductors (P and N-type) rather than just one type like a unipolar transistor. This allows for both electron and hole current flow in the device, giving it its bipolar characteristic.
What BJT stand for?
Unless it is some leet speak term I am not aware of, BJTstands for Bipolar Junction Transistor or (less common) Business Japanese Proficiency Test.
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
What is bjt and jfet?
BJT is Bipolar junction transistor FET is Field effect Transistor It is a current controlled device It is voltage controlled device
What is the difference between BJT and NPN transister?
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
What applications would prefer the bipolar junction transistors over the field effect transistor?
bjt is bipolar device whr fet is unipolar....fet is input resistance thts y fet gain is less compared to bjt..... The applications that will prefer bipolar junction transistors to field effect transistors are applications that require fast switching.
What are the uses of BJT?
Bipolar junction transistors has two junctions base emitter junction, base collector junction. Accordingly there are four different regions of operation in which either of the two junctions are forward biased reverse biased or both. But the BJT can be effectively operated in there different modes according to the external bias voltage applied at each junction. i.e. Transistor in active region, saturation and cutoff. The other region of operation of BJT is called as inverse active region.
Where can one get information regarding BJT?
If you have questions about Bipolar Junction Transistors (BJT), there are a small handful of websites. Indiabix, All About Circuits, and Research Gate are some places you can find information.
Is IGBT the bipolar device?
IGBT and BJT are bipolar devices as the name suggest. Meaning of bipolar device both electrons and holes leads to current unlike FET where either electron or hole causes current.
What is common collector bipolar junction?
A circuit in which the input signal is applied to its base and the collector is earthed (grounded) is known as common collector configuration of BJT (BiPolar Junction Transistor)
