amp

1a) Short for ampere, the amount of electrical current in coulombs per second which passes through a given point.

*brace yourself*

1b) The ampere is a constant current which if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1m apart in a vacuum, would produce between these conductors a force equal to 2 X ICT7 NirT1 length.

2) The thing that makes your electric guitar louder. Or a lot of other audio things come to that.

1) i work for siemens. x

2) My TV, PS3, PC, DVD player and CD player's audio all go through my Denon stereo amp and through 2 nice quality Ruark speakers.
