A transistor is an electronic component. By itself it has little use. An amplifier is a complete, functional circuit, generally made up of several components. A transistor can be a component part of an amplifier, however an amplifier may be constructed without any transistors (using vacuum tubes instead, for instance).
A: A transistor is a voltage amplifier and a tube is a current amplifier. A tube needs emission power to function a transistor does not.
A transistor can act as an amplifier. An amplifier you use for music might have many transistors as well as many other types of components. Transistors have other applications as well.
cascade: the output of one amplifier stage is connected to the input of another amplifier stages, it's also connected in series. cascode: it said to be cascode, when it has one transistor on the top of another where a common emitter transistor drives a common base transistor.
A vacuum tube is a current amplifier where the transistor amplifies voltageA tube is a voltage amplifier. A transistor is a current amplifier. A tube is an older design that requires substantial voltage to operate correctly. A transistor is a semiconductor device that operates on relatively low voltage.
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
Difference between oscillator and transistor
The first is a current amplifier with relative low impedance input The Second is a current amplifier of relative hi impedance input
single stage amplifier contain only one stage transistor amplifier but multi stage contain more than one amplifier stage
An amplifier is any device that changes, usually increases, the amplitude of a signal. while a transistor is a semiconductor device used to amplify and switch electronic signals. Hope this helps
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
A BJT is one type of transistor and POWER TRANSISTOR can be BJT or MOSFET or some other phenomena.POWER TRANSISTOR are usually those who are used at high current ratings e.g at POWER AMPLIFIER where large transistors are used at final stage to gain output.
A transistor can be used as an amplifier because the electrons in the base are multiplied by a gain factor to give the collector current.
That depends on both the input signal and the type of amplifier the transistor is used in.
it doesn't have to be. depends on design of amplifier using transistor.
Common Emitter - Class A Amplifier.
The output power of an amplifier is greater than its input power, whereas the output power of a transformer is almost the same as its input power. In other words, an amplifier increases acts to increase power, whereas a transformer only increases voltage.
A transistor used as a switch is operated in saturated mode, where the ratio of base-emitter current over collector-emitter current is far more than hFe, or beta gain. The transistor is either fully on or fully off in this mode. A transistor used as an amplifier is operated in linear mode, where the ratio of base-emitter current over collector-emitter current is equal to or less than hFe, or beta gain. The transistor is partially on in this mode, and is operating as a current controlled current sink.

The base controls the flow of electrons between the emitter and collector. A small current can control a larger current, which is the basic principle of using a transistor as an amplifier.
