An electronic device or electrical circuit that is used to amplify the signal is called an Amplifier. We can amplify sound, electric current etc. It is made up of Electron components such as capacitor, diode and transistor .
Capacitor
The Working of Sound Amplifier Is:In the following fig there are two main circuits. First circuit carrying a small amount of current represented by Blue lines and a microphone is attached to this circuit. In the second circuit, a battery is attached which is used to increase the current. These two systems are attached to the electronic circuit of the amplifier.
Electronic circuit
INPUT SIGNAL: - The input circuit is the electrical audio signal recorded on tape or running in from a microphone. Its load is modifying the output circuit. It applies a varying resistance to the output circuit to re-create the voltage fluctuations of the original audio signal.
OUTPUT: - In actuality, the amplifier generates a completely new output signal based on the input signal. You can understand these signals as two separate circuits. The output circuit is generated by the amplifier's power supply, which draws energy from a battery or power outlet Amplifier, device for increasing the amplitude, or power, of an electric signal. It is used to amplify the weak electric current drawn from the antenna of a radio-receiving set, the electrical signal representing sound in a public address system, and for many other purposes. One commonly used amplification device is the transistor.
Classification of Amplifier:Amplifiers are frequently classified by the type of electrical elements in the circuit. Inductancecoupled amplifiers are connected chiefly by coils and transformers; capacitance-coupled by condensers; and impedance-coupled by resistors. Direct-coupled amplifiers are connected directly, without such electrical components, and are used for alternating currents of very low frequency such as those that occur in many analog computers. The other types are used for a wide range of frequencies. Audio-frequency amplifiers operate at 0 to about 100,000 cycles per second (hertz), or 100 kilohertz (kHz). Intermediate-range amplifiers deal with frequencies from 400 kHz up to 5 million Hz, and so on.
