I have the following circuit with a 9V battery and two resistors, R1, R2, in parallel. Here is how it looks:
Are the following three ways all valid ways to represent this circuit?
- In the schematic, current flow is shown, which is always positive to negative.
- In #2 I've basically removed the negative terminal of the battery and put it at the bottom of the schematic.
- In #3, I've moved the negative side to the right of the diagram and smoothed out the lines, so it looks more like a graph/loop and less like a schematic.
If #3 is a valid way to depict circuits (which for me is the simplest to understand intuitively), what are some resources that show how to decompose a circuit into that?
