An amplifier is a device for raising the power of a signal by need of an external power source.

In an electronic amplifier, the input "signal" is generally a current or voltage. Other kind exist; a fluidic amplifier gain the power of signals shows as flow of liquid or gas, for example. Amplifiers can be categorized in several ways relaying on their application, the frequency range they wrap, or the current devices used. Ideally an amplifier amplifies the energy of a signal without otherwise modifying it.

 A device that changes signals from one signal to other is a transformer, a transducer, or a sensor. Though, none of these increases power. The basic intent was to acquaint you with biasing operations. Some of the diagrams were of essential amplifier circuits. That calculates amplifiers more nearly, but the subject is vast.
