yep the question isn't clear..

I am trying to simulate the attatched code for pic18f550 in proteus.Pin 20 of the port D is supposed to toggle after some time delay.Now when I try to simulate, proteus gives an error related to clock frequency, which can be set in the edit dialogue box. Now,i don't know much about...

Yes that's close to what I am confused about.Please explain a bit more the number line analogy and the term potential difference!

I am always confused with voltage polarities in circuit analysis.I can't really explain what I am confused about its just that i use intution rather than using a set rule to find voltage across some element bunch of elements.Most of the time the confusion is in applying KVL, and I am confused...
