The basic difference is the pin of the transistor that is grounded. The common collector has the collector pin grounded, common emitter has the emitter pin grounded and common base, as you guessed it, has the base pin grounded. The following article explains the differencnes perfectly.
Amplifier power is typically measured across a precision resistor, typically a Dale 8 Ohm power. resistor. These are precision high-power resistors that can dissipate lots of power. A sinusoidal waveform is applied to the amplifier input at various frequencies and the output. waveform is watched on an oscilloscope.
