moreover it can act as a resistor.they can amplify weak signals into strong signals.
in a chip which is used to run a computer or laptop there are millions of transistors cascaded in a chip which has size nearly of fingernail. you can find more information on YouTube

Why ordinary transistor is known as bipolar junction transistor?
Transistor is known as bipolar junction becoz it has 2 pole. Input is given to the 2 junction and output is taken from to junction
Is junction transistor and bipolar junction transistor are same?
Yes, the are different names for the same thing.
What is PNP?
it is a bipolar junction transistor having p-type emitter & collector terminal and , n-type base terminal .
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
Can fet be used as a transisitors?
No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.
What is a schottky transister?
A very high speed bipolar junction transistor having a metal-semiconductor emitter base junction instead of a semiconductor-semiconductor emitter base junction.
A bipolar transister consists of emitter and what else?
Bipolar transister consist of emitter base & collecter
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.
Why high noise in bipolar junction transistor?
In the case of Bipolar Junction Transistor current conduction is due to both holes and electrons. That's why noise is high in Bipolar Junction Transistor
Why ordinary transistor is known as bipolar junction transistor?
Transistor is known as bipolar junction becoz it has 2 pole. Input is given to the 2 junction and output is taken from to junction
Why is a transistor a NOT gate?
A normal configuration for a BJT is Class A Common Emitter. In this configuration, the BJT operates as an inverting amplifier. Driven into saturation, it is a inverting switch, hence the designation NOT gate.Transistor can act as a gate. But its not a gate. In BJT(Bipolar Junction Transister) type transisters there are two P-N juntions. That means if we need we can use it as a NOT gate. Actually gate ICs (Intergrated circuits) are also build using transistors. (Example : TTL(transister-transister logic))
What is the most probable junction in transistor maintenance circuits and is it base or base and collector or emitter and collector?
Most probable junction in transister is base emiter
Do people use bipolar junction transistor today?
Yes people still use bipolar junction transistors today because of its high switching speed.
Is junction transistor and bipolar junction transistor are same?
Yes, the are different names for the same thing.
When wassemiconductors first invented?
The Bipolar junction transister was invented in 1947 at Bell Labs. This was actually the first successfully constructed semiconductor device. But the theory and idea for semiconductors went back to the mid 1920's, and the first patent for a semiconductor device was issued in about 1936 to Julius Lilienfeld.
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)
Can a transister base-emitter junction be used as a zener diode?
No, the doping profile is entirely wrong. Also some transistors have very low reverse breakdown voltage on the BE junction and will burn out!
