Hello All,

Trying to get my head around some theory to prepare for my catch up exam on electronics stuff. Anyway, i have attached an image since in circuit analysis we assume that the voltage is the same everywhere in a wire (before we reach a circuit element), this should imply that both the Va are at the same voltage right? Lets say its 4V, hence the potential difference between these two points is 0 right? So we have no electric force therefore shouldn't there be no current flow? - However doesn't this contradict the meaning of short circuit which says that if the voltage between two points is 0 then a lot of current flows.

To summarize the question - If two points in a wire are at the same voltage then the difference between them is 0 and this is a short circuit which causes a lot of current to flow however if we have 0V between two points then we have no electric force hence no current flows?

All help is appreciated.
