Amp-amplification law
The job of an amplifier is obviously to amplify, but the law it abides by isn’t so simple.
Ultimately, the amplifier is comparable to a valve, in the sense that using a small effort in turning the valves’ handle will control a large flow.
Therefore the core principal and law that amplifiers abide by is not somehow making a small current large, but rather using a smaller current to control a larger flow.
