A: There is a misconception of understanding of terms here. A power amplifier is called that because it has capabilities to derive power from it .It does not create power it actually uses more input power then the power delivered, In other words it has a decrement in efficiency

What is the purpose of amplifiers?
Obviously is to amplify signals
Difference between amplifier and power amplifier?
Voltage amplifiers are genrally used to amplify voltage signals to a certain db and amplification is a linear process. In power amplifiers it is not required to amplify voltage it is not significant and genraly equal to input voltage. It is significantly used to produce a large current at the output.
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.
What is the function of amplifiers?
A: Obviously is to amplify or to create a function to be used
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 are the uses of an alpine amplifier?
Alpine amplifiers are used to amplify sound of digital equipment such as Subwoofers. You can purchase Alphine amplifiers online from retailers such as Amazon.
What is the average frequency range for bass amplifiers?
Bass amplifiers are used to amplify the music that comes from a bass guitar. The average frequency range for bass amplifiers is between 25 and 250 watts.
What is difference between ac and DC amplifier?
AC amplifiers are used to amplify AC signals and use components that handle large voltage values. DC amplifiers are used to amplify DC signals which use small powered electronic devices.
Does a audio mixer amplify sound?
Most mixers do not amplify the sound. However, there are some rack-mountable ones that do amplify it. If you are working with a regular mixer, you will need amplifiers built into your speakers or a separate amplifier
Is it possible to amplify mechanical power?
Yes, it is possible to amplify mechanical power by preserving the input power.
Which quantity does a transister amplify?
Depends on the circuit the transistor is used in:it can amplify voltageit can amplify currentit can amplify power
What 3 things does an electrical amplifier amplify?
An electrical amplifier amplifies 2 physical quantities according to the transistors used. If a BJT is used it amplifies the current and if a MOSFET is used it amplifies the voltage. Hybrid amplifiers amplify current as well as voltage so in theory , current voltage and power is amplified.
