An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals...

Amplifiers, like all machines, are limited in efficiency to a maximum of 100 percent. The requirement of an external source of power is common to all types of amplifiers, electrical and non-electrical.

Electronic amplifiers or "amps" are devices that increase signal power. Understanding amplifiers is key if you want to be an electrical engineer or simply learn to tweak your audio system.

It may seem like an audio add-on, but without an amplifier, you'd never be able to hear the music on your CDs (your neighbors might be happier, but would you?). Find out how amps pump it up to 11.

Stereo amplifiers receive and enlarge small electrical signals. In cases of power amplifiers, signals are amplified much more to power a loudspeaker.
