SUMMARY
The discussion centers on calculating current in a series circuit involving a 2.0 Ohm resistor, a 5.0V battery, and an internal resistance of 0.5 Ohm. The initial calculation using the formula V=IR led to an incorrect conclusion of 2 amps. Participants highlighted that a voltmeter, designed to measure voltage with minimal current flow, complicates the scenario, indicating that the question lacks clarity and completeness. The consensus is that the circuit's configuration and the role of the voltmeter render the problem unsolvable with the provided information.
