Thanks for your help.
I think I may have been a bit misleading with what I was trying to do.
I'm just trying to provide a circuit that shows the basics of resistors / resistance, voltage and current. It's not really meant to be an explanation of how movement works.
The meter in the diagram was not meant to be an ammeter at all. The one I have here that I've been testing with is actually a voltmeter, so it doesn't need to be converted. Connecting a battery directly to it would give a correct reading, as long as it's in the correct range.
I based my work on a sample circuit in a website () which has the resistor networks in it.
Are they wrong, or is it just unnecessary?
I've made some changes, but not all. I wanted to clear up the misconception first. I've attached the document with some of the changes made. Let me know what you think, and I'll go from there.
Thanks very much for your help
