A Geiger counter, also called a Geiger-Müller counter, is a type of particle detector that measures ionizing radiation. They detect the emission of nuclear radiation: alpha particles, beta particles or gamma rays. A Geiger counter detects radiation by ionization produced in a low-pressure gas in a Geiger-Müller tube

Why bjt is bipolar?
Bjt is bipolar because in bjt the conduction of current is due to the electrons as well as holes
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 is the difference between jfet and bjt?
FET's (field effect transistors) are unipolar devices because unlike BJT's that use both electron and hole current, they operate only with one type of charge carrier. BJT is a current-controlled device; that is the base current controls the amount of collector current. FET is a voltage-controlled device, where voltave between two of the terminals (gate and source) controls the current through the device. BJT's have a low input impedance ( ~1k -3k ohms), while FET's have a very high input impedance (~10^11 ohms). Consequently FET's have a lower power consumption. BJT's produce more noise than FET's . FET's have a slower switching speed . BJT's are subject to thermal runway while FET's are immune to this problem. BJT's have a higher cutoff frequencey and a higher maximum current then FET's. FET's are easy to fabricate in large scale and have higher element density the BJT's.
Is BJT used for high speed power application?
Yes
Which is used for high speed application bjt igbt mosfet triac?
supposed to be MOSFET. but i also depends on your working freq.
Can UJT replace BJT?
No. A unijunction transistor (UJT) is entirely different in design and application than a bipolar junction transistor (BJT). The UJT works on the principle of voltage modulation of the effective substrate resistance, while the BJT works on the principle of current amplification from one junction to the other, usually base-emitter to collector-emitter.
Why bjt is bipolar?
Bjt is bipolar because in bjt the conduction of current is due to the electrons as well as holes
Why fet is preferred over the bjt?
Disadvantage:Easy to damage when compared to BJT
What are the example current controlled device?
Bipolar junction transistor(BJT)
What is the difference between BJT and NPN transister?

Applications of hybrid pi model of bjt?
ApplicationsThe BJT remains a device that excels in some applications, such as discrete circuit design, due to the very wide selection of BJT types available, and because of its high transconductance and output resistance compared to MOSFETs. The BJT is also the choice for demanding analog circuits, especially for very-high-frequencyapplications, such as radio-frequency circuits for wireless systems. Bipolar transistors can be combined with MOSFETs in an integrated circuit by using a BiCMOSprocess of wafer fabrication to create circuits that take advantage of the application strengths of both types of transistor.
What is the typical base-to-collector amplification factor of CA3046 BJT?
The typical base-emitter gain (beta or hFE) of a CA3046 is 100, at an emitter current of 100ma. This translates to a base-collector gain (alpha) of 0.99.
How many terminals does BJT have?
Three.
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
