Re: Beginner's question: NPN common-emitter amplifier setup?

I have seen schematics with a resistor hooked up between the emitter
and ground. In a book by Stan Gibilisco (I can't remember the name
off hand) it stated that although the emitter was grounded from the
signal that there was still a voltage due to the resistor. Is there
a voltage because:

When the collector draws current from the emitter, that current passes
through the resistor creating a voltage drop? I don't think that
polarities are correct.

If this question doesn't even make sense to you guys, please let me
know.
