SUMMARY
The discussion centers on the calculation of the voltmeter reading (V') when measuring the potential difference across a resistor (R) in a circuit. The formula derived is V' = Ir/(R+r), where r is the resistance of the voltmeter. The participants emphasize the need for a circuit diagram to clarify the configuration of resistors and confirm that the total current remains constant (I' = I) for accurate readings. Additionally, there is a note on the dimensional correctness of the equation, indicating a potential typo in the solution.
