Seriously,though,this a silly question.

Just Google for Power Amplifiers & you will find many references to the use of such amplifiers.

If this is a formal homework question,surely somewhere in the course,you will have been taught about this.

Power Amplifiers are extremely important in many aspects of Electronics,from mobile phones,to satellite Earth Stations.

You use a power amplifier if you need to micro-step a stepper motor in a robotics application, or drive a coil in NMR ( nuclear magnetic resonance), MRI (magnetic resonance imaging) or EIT (electrical impedance tomography).
It is required to drive the spindle motor and linear head seek motors in disc drives.
