The change of collector current with respect to emitter current.
Typically 0.95 to 0.995. So a transistor with alpha of 0.95 might have an emitter current of 10 mA, collector current 9.5 mA.
The "missing" current becomes base current and does not reach the collector.
The more commonly used figure for current gain is beta, the ratio of collector current to base current, typically 50 to 500.
In CB MODE
It is called the common base, short-ckt, amplification factor.

Is bipolar transistor is made up of one NP junction?
no, 2 junctions. NPN or PNP
How we check Bipolar junction transistor with digital multimeter?
By testing the C B E terminals.
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
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
Is junction transistor and bipolar junction transistor are same?
Yes, the are different names for the same thing.
What is the alpha beta teta of a bipolar junction transistor?
alpha is the common base current gain = Ic/Ie.beta is the common emitter current gain = Ic/Ib.
How do you test the bipolar junction transistor?
through the used of multi-tester

Do people use bipolar junction transistor today?
Yes people still use bipolar junction transistors today because of its high switching speed.
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)
