I am trying to make an audio amplifier using the lm741 op amp, and I want to measure its output impedance , so that I can attach a speaker of matching impedance,

this way I think, I will be transferring more power,,

but how do I measure the output impedance of my circuit,

also are there any bandwidth considerations to keep in mind when using the lm741
 

i have tried making an audio amplifier using lm741 and strictly advice against it.... slew rate is a very big concern for audio amplifier and so my signal was very distorted....

for finding the output impedance just calculate the output voltage by current...
