about common emitter amplifier operation

What about it?

He needs someone to do his homework for him, of course. But he's either too lazy to even construct a proper question, or he's so lost he doesn't even know what to ask. Either way, I guess he's toast.

The gentleman should consider switching majors to journamalism. He seems to have the skillset down pat.

Add the keyword tutorial to those words and Google.

Get a dictionary, and look up the word "common". Then look up the word "emitter" (hopefully it's a recent enough dictionary that it will give mention to bipolar transistors) and then look up the word "amplifier" Maybe look up "transistor" for any insight that definition might give.

Then perhaps the term will mean a bit more. Likely a dictionary specific to electronics (do they still publish those?) would provide a definition of what it is.

If not, then figure out what it might mean. Keep in mind the various elements of a bipolar transistor (we know it's a bipolar since only those have emitters), and what might happen if one of the other elements were common.

ANd then once you've figure out what it is you want to ask, and can phrase it properly, then maybe whatever it is you want to ask (we are not mindreaders) would be worthy of a real answer. Maybe not, depending on whether you can show you've made a stab at understanding and trip over some bit, or if you don't want to do any work yourself and expect us to not only guess what it is you are asking, but provide the answer. If we can look it up in books, so can you.
