The transistor was not discovered, it was invented.
The first patent for a transistor was filed in Canadaon October 22, 1925. The device was a FET and although some prototypes apparently worked the device was never commercialized and sold.
The first practical transistor was invented on November 17, 1947 at Bell Labs while attempting to recreate the FET. However this device was a bipolar point contact transistor instead. Early in 1948 another researcher at Bell Labs invented the BJT. Both point contact and BJT types of transistors were rapidly commercialized by Bell Labs and sold by many companies.
The first practical FET was invented in 1953 at Bell Labs.
I believe in the 40 it was not invented but discovered by two BELL LAB engineers. YES it is a USA discovery. Was never an invention.
A silicon transistor is a transistor made of silicon.
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
A Unijunction Transistor is a transistor that acts solely as a switch.
Similar to a 2N3906 PNP transistor
how does a transistor behaviour
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
I believe that is resistor transistor technology TTL transistor transistor logic
I can give you several sentences.I bought a transistor radio.The transistor amplified the signal.We studied the transistor in science class.
A Darlington pair uses two transistors connected to behave as a single transistor with a very high current gain (beta). Transistor-1 has its collector connected to the collector of transistor-2. Transistor-1 has its emitter connected to the base of transistor-2. The base of transistor-1 with the emitter and collector of transistor-2 is used as a single transistor.
no is not !
the best way is to compeair the data sheet of that transistor to the readings of that transistor. . . . .and u can get the readings of that transistor by using a fungction genrator and a c.r.o
