The question seems to be vague and incomplete. So, I am giving a general and an assumed answer.
Based on their mode of operation, the power amplifiers are classified as Class A, Class B, and Class C amplifiers.
The Class A power amplifiers are always forward biased. In this class of amplifiers, the collector current will flow throughout the full cycle of the signal and so, it is biased in a way that even a single part of the signal is not cut off.
The Class A amplifier has lower efficiency and so it not used much for higher power output stages. The active device is 'ON' all the time. A majority of the DC power is wasted and is lost in the form of heat on the transistor or the active elements.
