What else can I help you with?
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.
What happens when high input signal is given to pnp transistor?
A high signal input to a transistor amplifier gives a high signal output provided it stays linear.
What is stage gain in a C-E amplifier?
Stage gain in a common-emitter (C-E) amplifier refers to the amplification factor of the input signal as it passes through the amplifier stage. It is typically defined as the ratio of the output voltage to the input voltage, expressed as a voltage gain (Av). In a C-E configuration, the stage gain is generally greater than one, indicating that the output signal is amplified relative to the input. The gain is influenced by factors such as the transistor's characteristics, resistor values, and the load connected to the output.
What is the output signal of a common base amplifier?
3Db
What is the function of resistor in single stage amplifier?
A simple, 1 transistor single stage amplifier can be made using several resistors to bias a NPN or PNP transistor into its' linear operating region. With this done, a small voltage signal applied to the input of the amplifier will have the voltage amplified at the output in a linear fashion. I'm not sure what your question is; if this does not answer it let me know.

How work amplifier?
amplifier consists of active components like transistor fet etc,. for example transistor, it produces high output is common emitter configuration. when u give weak signal to the base of the transistor and the output is taken in collector terminal(amplitude of the weak is increased, so the output is high ) its known as amplifier
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.
What is common collector bipolar junction?
A circuit in which the input signal is applied to its base and the collector is earthed (grounded) is known as common collector configuration of BJT (BiPolar Junction Transistor)
What is difference between transistor and amplifier?
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).

How does a transister work as an amplifier?
The name is your clue: a transistor and a resistor (the load) are put in series. The output signal is taken from the load resistor. A small input signal (to the third lead of the transistor) will cause the transistor to change resistance ... thus you can get a large output from a small input Amplification.
What is the output signal of a common base amplifier?
3Db
What is an emitter follower?
This is a particular transistor amplifier configuration. In general, the input signal is applied to the base, the collector is connected to a supply voltage, and the output is taken between the emitter and power supply common. One of the characteristics of the emitter follower is the output voltage "follows" the input, but the output is reduced by the Vbe voltage (the voltage drop between base and emitter, approximately 0.7 V for a silicon bipolar transistor).
What is the meaning of transistor as an amplifier?
the electrical signal coming out from the micro phone is very low &this cannot drives the loud speaker.For this purpose we incresing the signal level which is coming out from the microphone (usually an Ac signal)is known as amplifier.it cannot incresing this signal level without using external energy(as per law of conservation of energy rule)For this we use external dc energy.only the device which can convert the external dc energy into ac energy is transistor. so we say transistor as an amplifier
How is negative feedback achieved in a single stage transistor amplifier?
A: Feedback is a signal fed back from the output like from collector to the base .
