Common Emitter Transistor Amplifier for Mic

I am pretty new to electronics, and I have started home study a while ago. One of the things that gave me trouble is the CE Amp, because without the proper values inserted I could not build one in EC to figure out what the circuit is properly supposed to do. I think I have done it now, thanks to this handy and well detailed guide (http://youtu.be/Br3uOM0IVjc) which I partially reproduced in my circuit. The oscilloscope compares the input voltage waveform of the source with the one on the 10uF C. I inserted extra the 1uO resistor on the base just to be able to measure the Current, and the switch for the Mic bias resistor. Few questions for the pros: 1. Is this the way a CE Amp is supposed to function? 2. What is a Mic bias and why is there supposed to be current there? Thank you for answering!
