hmmmm, all mics are "electric", you may have ment "electret". these run on on abt 2-5 mA of current witha typ 2.2K series load res..radioshack used to have data on these items in educational books. remember it's only a mystery till you figure it out and it's science not magic. get to using your library...look at the ARRL hand book. the newer version will have a section on mics. Sony started to produce electrets in the 1970's after they solved the problem of keeping the charge constant. nothings easy!

They vary, but usually the signal is in the order of a few millivolts. If you connect the microphone to an o-scope, you could see for yourself.

It depends on the type of microphone and the sound level coming in. It's usually tens of microvolts to a few millivolts.

expect it would be in micro volts
You are going to need to amplify it to do anything useful with it.
