The extra power come from the external source of power we attach to the amplifier.

  • The property of amplifier states that the it is related to the voltage amplifier or current amplifier and also the product of both
  • The both quantity are directly proportional to amplifier.
  • So the power is the related to the product of above both quantities
  • As the current and voltage increases the power also increases.
  • Which means if we provide and external source of supply the output of the system get amplified
  • But the phase and frequency remain same.
