A transistor has three sections, an emitter, base, and collector. By extracting a small number of electrons from the base, a large # of electrons can flow across the transistor from the emitter, thru the circuit, and back to the collector.
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.
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
at full input, if the transistor is working, the value of capacitor will be 0.

A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
That depends on both the input signal and the type of amplifier the transistor is used in.
When transformer is used in step up mode then we can use transformer as amplifire
When transformer is used in step up mode then we can use transformer as amplifire
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.
it is a combination of two transistors connected in series. the emitter of transistor t1 is connected to the base of transistor t2 . now the total circuit acts as a single transistor. this combination will gives high gain, as the gain is multiplied.

Common Emitter - Class A Amplifier.
A Unijunction Transistor is a transistor that acts solely as a switch.
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.
transistor has 2 output 1 and 0 so can be used as a switch
