based on the circuit kung 9 volts yung nasa supply rail, tapos ang maximum output current ng 741 (if ever 741 nga ang gagamitin mo)based on data sheet is 25mA lang.. around 1/4 watts lang siya.. correct me if im wrong..

the audio amplifier shown is not designed to drive a speaker load. It can be used as part of a preamplifire circuit but not as an output stage to drive a speaker. Connecting an 8 ohm speaker to this circuit will overload the 741 IC.
