# Notation for marking the voltage drop in this picture

## Homework Statement

When we write the V_0 on the right of the diagram as show below, between which two points does the voltage drop refer to? There are two nodes on the top correct? I am assuming the voltage drop refers to the two rightmost nodes.

I've tried to circle the nodes.

It's just a notation question.

## The Attempt at a Solution

It's not a homework problem.

Good assumption.

Boy, what a lousy problem.

What is the rule for the notation in general?

Is it common to just mark voltage as height on the paper as opposed to between specific nodes?

Are there standard conventions/notations for circuit diagrams? I'm certain there almost have to be. Are they universally applied? Not in the 50 odd years I've been deciphering them. Check NEMA, IEEE, Giaccaletto, Kaufman & Seidman, who else .....

Because it's written beside an element, I'd say in general a marked voltage will be the voltage across that element. Yes, in this case it follows that it's the potential difference between the rightmost nodes.

And that element is the current generator. So the marked voltage is across it.
