How transistor acts as a amplifier?
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
When transistor acts as an amplifier then does its output voltage increase or decrease?
That depends on both the input signal and the type of amplifier the transistor is used in.
How does transistor acts an amplifier?
When transformer is used in step up mode then we can use transformer as amplifire
Why a transistor acts as a switch?
Only because the circuit that its embeded in is designed that way. Remember, a transistor is basicly an amplifier ... only if you design everything to go to the extreams will it act as a switch.
When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
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.
What is the working of a Darlington 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.
What component is typically used as an amplifier?
A transistor
Why the gain of pnp transistor is low?
it doesn't have to be. depends on design of amplifier using transistor.
What configuration commonly employed in bipolar transistor amplifier?
Common Emitter - Class A Amplifier.
Difference between cascode and cascade amplifier?
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.
Why a transistor is used as a amplifier and switch?
transistor has 2 output 1 and 0 so can be used as a switch
What is the purpose of the Unijunction Transistor?
A Unijunction Transistor is a transistor that acts solely as a switch.
