1. As amplifiers, usually as current amplifiers, but sometimes to amplify the voltage instead (where a FET is typically used). Think of the amplifier in a stereo system for example.
2. As switches. Usually as part of an Integrated circuit, although discreet components can be used to make individual switches. Think of solid-state relays for example.
3. As a buffer or impedance matching between mis-matched circuits. Think of the input to an oscilloscope circuit, where it has to load the circuit under test only very lightly.
4. As a regulator. This can be to regulate current, voltage, or power. Think of power transistors in the power supply for the stereo system for example.

What are transistors used for?
Transistors have two basic functions: # an electrically controlled electric switch # an electrically controlled "proportional valve" which can alter currents and voltages, or can amplify electric signals. Transistors can also be configured as Oscillators which provide an AC signal with constant frequency. Either an amplifier circuit or a switching circuit can be wired as an oscillator. Transistors can be used to form logic gates: And, Or, and Invert. Computers are made from logic gates, so computers can be made entirely from transistors. Transistors are in use in virtually all electronic devices. PC processors are composed of millions of tiny transistors. A transistor radio may have had only 6-10 transistors to enable operation. A late model car may have 10 to 15 computers comprised of thousands of transistors to perform all manner of operations in the vehicle.
How many transistors are on a Phenom II 965?
758 Million transistors.
How many transistors used in core 2 quad and in core 2 duo?
From an AnandTech article the answer appears to be 582 million transistors for the Quad, 291 million for the Duo. Reference: http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2866
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
What is an electronic component used for?
An electronic component is simply used to resist the flow of a certain current. In theory, it is connected to a circuit board and includes those resistors, capacitors, and transistors.
What elements are used in transistors?
Silicon and germanium are the elements used in transistors
What are power transistors?
Power transistors are transistors that are used in high-power amplifiers and power supplies.
What are transistors used in?
Transistors are used in any electrical somponent including amplifiers, remote controls etc.
What element are in transistors?
Silicon and germanium are the elements used in transistors
What elements in in transistors?
Silicon and germanium are the elements used in transistors
Why are npn transistors used more often than pnp transistors?
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
Why transistors are not used for switching devices?
Transistors are used for switching devices! What gave you the idea they aren't?
What substance is in sand that is used in making transistors?
Silicon is the substance in sand that is used in making transistors. Silicon is used as the raw material for producing the silicon wafers, which are then processed to create the transistors.
Why base is used in transistors?
TWO
What is germanium used for?
It is used in transistors and other electronic devices.
Which transistoris widely used?
Npn transistors are widely used
Why do transistors sometimes need heatsinks?
These types of transistors are power transistors and generate heat. The heat sink is used to dissipate the heat. If the transistor gets too hot it will fail.
