-An Amplifier is a device which uses a small amount of power to control a source of a large amount of energy.
+An Amplifier is a device or circuit that converts a small signal, voltage or current, into a larger signal, voltage or current.  Amplifiers are typically built from discrete devices like tubes or transistors, or are manufactured as a IC device to reduce components or complexity.
+You will generally run into three amplifier types on the MERG forum or with MERG kits; a transistor as an amplifier, an Operational Amplifier (op amp) such as an LM324 or an audio amplifier such as an LM386.
