hackhater's post is very helpful. Perhaps this thread will become a sticky.
[QUOTE=scruffboy]Tell me if I understand this correctly. Infinite resistance means a closed circuit, no electricity flowing? Is that correct?
Infinite resistence is what you'll read on the ohmmeter when there is an 'open' in the circuit you are testing.
Read all about it here.

If you took a piece of wire and placed the red lead on one end, and the black lead on the other end, the meter will read 'some' resistance in the wire. The metal the wire is made from will slow down the flow of the electrons passing thru it.
This whole area of electicity, and current flow, and resistance can get very interesting, and complicated.
