How do I get output impedence of ICs?

@ScottSeidman: But to get the cutoff frequency don't I need the exact resistance value?

Speaker should give some output right?

I don't get any voltage difference in the output capacitor using DMM. I checked the polarity it's fine.

sorry- there is a typo, it's 2KOhm.

It doesn't come with a datasheet

Why doesn't this transistor circuit work as expected?
Got it. Is it just for collector base? What if I short Emitter-Base? Is that also a diode equivalent?(In general, not in this circuit)

Why the current goes to capacitor? If the transistor is ON , current has got least resistance path through Collector-Emitter, so even the capacitor should discharge through this path. Wrong?

@IgnacioVazquez-Abrams: But what about the Hz measurement of multimeter. It is also giving zero. Atleast this has to work?

Why is resistance across my arm-span so much less than across my face?
I am more resistive than you across my hands. Mine is 1Mohm :)
