What else can I help you with?
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.
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 a PNP transistor is connected in a circuit in the manner it can be used as a power amplifier because?
the output voltage will be much larger than the input voltage
When a PNP transistor is connected in certain circuit manner it can be used as a power amplifier because?
not sure if this is the answer : the output voltage will be much larger than the input voltage.
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.
Why is npn transistor called emmitor follower?
In an NPN transistor an emiter follower refers to an amplifier topology. The emiter follower configuration is when the emitter of a N-Type Bipolar Junction Transistor (BJT) is connected to the common point on a circuit (typically ground). This is not always the case, however, because many amplifier configuration exist.
A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased This transistor can be used as a power amplifier?
Yes1
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
In a well-designed circuit the transistor will act like what?
Voltage amplifier
What should be the value of capacitor at transistor amplifier circuit input?
at full input, if the transistor is working, the value of capacitor will be 0.
Why can a PNP transistor be used as a power amplifier if it is connected into a circuit in a manner such as that shown in the book Electricity and Electronics Figure 52?
A PNP transistor can be used as a power amplifier in a circuit because it can handle high power levels and provide amplification by controlling a large current with a small input signal. In Figure 52, the PNP transistor is configured in a common emitter configuration, allowing it to amplify the input signal by controlling the current flowing through the load connected to its collector terminal. The transistor acts as a switch that modulates the output current based on the input signal, providing amplification of power.
Is transistor a current amplifier or voltage amplifier?
depends on the circuit it is used in:CE/CS is inverting voltage amplifierCC/CD is noninverting current amplifierCB/CG is noninverting voltage amplifier
