a transistor is called a Bi-polar device because in this we use both p-type semiconductor and n-type semiconductor.
In p-type semiconductor the current flows with the help of holes(deficiency of an electron or we can say it as a positive charge).
while in n-type semiconductor the current flows with the help of electrons(negatively charged particles).
so the total current is due to both kind of charge carriers.
that's why it is known as a Bi-polar device.

What is the function of the legs on a transistor?
as the name suggest transistor means to transfer resistor, it is an electronic device,
Why the transistor is not used in switching 'AC voltage'?
The transistor is a "single direction current flow" device. Typically, for an NPN device, the collector must be more positive than the emitter for the device to bias on. You could use the transistor in an AC circult, but it would only conduct on half the cycle.
What is a electronic device that is made of solid mateiral which electrons move through?
Any semiconductor device...eg: A transistor.
What is mining of transistor?
A transistor is a device used to switch power between electrical components. Transistors work to amplify existing signals as well as open and close circuits.
Why you mention diode is a nonlinear device and transistor is a linear device?
since the diode shows its characteristics in a non linearly it is called as nonlinear element since the transistor shows its characteristics in a linear way it s called as linear element Transistors are typically operated in their linear region (such as when used in amplifier circuits), or as switches (where you will in general ignore the nonlinearity of the transistor). Transistors are typically DC biased to operate in this linear region. Diodes are not biased in this way. Strictly speaking, both are nonlinear devices, although transistors can be used in their linear operation region, while diodes are not.
Why transistor is called as bi-polar device?
Transistor is called Bi-Polar device because the current can be flow due to electron and holes, hence it is called bipolar.
Why UJT is called as transistor?
Even though it has only two types of charge carriers we will not call it as a diode but a transistor since it is a three terminal device.
Why transistor is called transfer of resistor?
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
What is the difference between transistor and processor?
Transistor is an tiny electronic device called electronic switch,which is building block of a processor. Processor is a data processing device consists of thousands or millions of transistors. Eg- Intel 8086 microprocessor has around 29000 transistors.
What is the difference between a switching transistor and an ordinary transistor?
In the switching transistor the output current is controlled by the (current) and this is also called current controlled current device (CCCD). But in ordinary switch we controlled output current physically...
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
Which device revolutionized the computer industry?
The transistor.
What is the simple device that opens and closes an electrical unit called?
A device that opens and closes a circuit is called a switch.
Whether the transistor is linear or nonlinear device-?
Very nonlinear. If you need operation approximatinglinearity, a transistor must be limited to a very narrow range of operation.
What does a transistor look like?
Transistor is a three terminal device. Its shape may differ with applications.
What is the function of the legs on a transistor?
as the name suggest transistor means to transfer resistor, it is an electronic device,
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
