Is there a better way of presenting circuit diagrams to our students that will aid their understanding of potential difference?
I think that, possibly, there may be.
(Note: circuit diagrams produced using the excellent — and free! — web editor at https://www.circuit-diagram.org/.)
Old ways are the best ways…?
This is a very typical way of showing a simple circuit.
Now lets measure the potential difference across the cell…
…and across the resistor.
Using a standard school laboratory digital voltmeter and assuming a cell of emf 1.5 V and negligible internal resistance we would get a value of +1.5 volts for both positions.
Let me demonstrate this using the excellent — and free! — pHET circuit simulation website.
