Why are transistors called transistors?
it is nothing more than a semiconductor device through which currents and voltages of the desired magnitude can be obtained.
- It can be used as a switch as well as an amplifier.
- it makes it versatile and the range of applications it offers is huge.
because in this device, the resistance between two terminals, respectively collector and transmitter, is modified by changing the base voltage, that is to say, it transfers the resistance between transmitter and collector; it is therefore called transistor.
transistor is a combination of the words transfer and resistance called transistor, it is so called because it is a resistor or a semiconductor device capable of amplifying the electrical signals when they are transferred from the input to the output terminals.
The name of the transistor is briefly given name of the transfer resistor. now transistor how to transfer resistance is question. its answer is that the transistor has a very high input resistance and a very low output resistance due to its internal structure.
the transistor name means approximately trans-resistor, all transistors have three terminals. a terminal is a control terminal. the voltage on the control terminal (or the current flowing in the control terminal) modulates or controls the resistance between the two remaining terminals. hence the name trans-resistance or transistor!
it is the abbreviation of the term ‘trans-resistance’
the ratio of variation of the current of the collector on the variation of the input voltage vbe in a small signal amplifier is called transconductance and conversely, it is the trans resistance
This simply indicates that a small voltage at the input produces a large change in the collector current.
The transistor name is derived from the transfer resistor, it means that the resistance is changed. it is a solid state device composed of silicon and germanium. Therefore, the function of a transistor is to change the resistance for various applications using its specifications.
This is how the name of transistors is born.
The transistors can be used as an amplifier or as an electronic switch.
the transfer of the resistor is a transistor – the base-emitter junction is directly polarized and therefore has a low resistance to the conduction of the emitter at the base the base collector junction is reverse biased and therefore has a high resistance.
The direct-reverse bias combination causes the thin base region to decompose due to the base collector junction reverse bias to drive from the base to the collector, thus making the high-resistance region a low-resistance region. ; that is, the transfer of the resistor
The origin of the name “transistor”
Transistor has two pn junctions. one of the pn junctions is forward biased and the other is reverse biased. the junction which is forward biased has a low resistance path and the reverse bias junction has a high resistance path. the weak signal to be amplified is introduced into a low resistance circuit and is extracted from the high resistance circuit.
Therefore, a transistor transfers a signal of low resistance to high resistance. the trans prefix is the transfer property of the device and istor shows that it is the solid element of the same family of resistors.
transistor: as its name comes from resistors with transfer properties or simply amplification of the input function, it is called transfer resistor commonly called transistor.
mainly transistors are two types that are pnp and npn.
By working as a switch and as an amplifier as well, amplifying here means transferring the resistance of the emitter to the collector and the collector base.
by these transfer functions of resistance is called the transistor.
