Operational Amplifier Tutorial & super microphone circuit

Afroman goes over the basics of how to use an operational amplifier to amplify tiny voltages, and builds a circuit to listen to very faint sounds with a microphone. Don't forget to vote 5! For more information about amplifiers, Google "inverting amplifier" "non-inverting amplifier" "instrumentation amplifier" "class A amplifier" "class B amplifier" "class AB amplifier" and that should give you a lot to chew on.
