A transistor controls the flow of current between the emitter and collector.
The larger current is supplied by the power supply, across the emitter and collector.
The flow is then controlled by a small current applied to the base connection.
So, a large current flow mimics the small signal current.
Limits are reached, when the transistor gets close to being fully switched on or off. This will cause distortion. To avoid this, more amplification is provided by a series of transistor amplifiers, one after the other.
What else can I help you with?
What are the propeties of transistors?
A: It amplify voltage depending on configuration
Which combination of n-type and p-type semiconducters would be used to amplify a weak electronic signal?
n-p-n
Will semiconductors amplify the electric signal in a transistor?
Actually, a transistor is a device made from semiconductor material, and they're used to amplify and switch electronic signals as well as electrical power. Before transistors were invented, product engineers had to use vacuum tubes and electromechanical switches in order to complete electric circuits.
What are advantages and disadvantages of multistage amplifier?
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
What are the differences between analog and digital transistors?
transducer convert one energy to other energy .now in analog transducer it convert energy use of analog signal and digital it converts use og digital signal
What are transistors used in a mobile phone?
they amplify the phone's incoming signal
What is the primary use of transistors in a mobile phone?

What is the main work of transistors in an electronic circuit?
The main use of transistors in electronic circuits is as switches and memory storage
What do transistors do in a circuit?
Transistors provide most of the activities a circuit needs to operate. In their most basic representation, transistors are amplifiers. That is, they take and amplify a signal from the level produced by a microphone and amplify it enough to blast it out through a speaker. Transistors are also used on decision making circuits, like electronic gates and Central Processing Units (CPUs). Solid state, electronic systems like desktop computers, cell phones, and GPS devices would not be possible without transistors.

What is the purpose of an AF power amplifier in a FM broadcast receiver?
After FM demodulation to the original AF signal it is necessary to amplify the weak AF signal to have enough power to drive speakers. That is the purpose.
Why amplifier is required?
Amplifiers are the device which are used to amplify a signal Multistage amplifier are use to amplify a signal into a desire level
What is the verb for amplify?
Amplify is a verb. This device amplifies the signal from the microphone so that it can be heard.
Will semiconductors amplify the electric signal in a transistor?
Actually, a transistor is a device made from semiconductor material, and they're used to amplify and switch electronic signals as well as electrical power. Before transistors were invented, product engineers had to use vacuum tubes and electromechanical switches in order to complete electric circuits.
Why do you supply DC power?
DC power supply is used to power the IC's and other active and passive devices.It is provide to amplify the weak signal with the help of amplifiers.
