If you connected the positive terminal of a battery to the negative terminal to a battery with a wire with (hypothetically) no resistance, and are asked to give the voltage drop of a segment of wire in the circuit, how would you determine this?

If you are asking what happens when a constant-voltage source with infinite current capability is short-circuited by 0 resistance, it's not a well-defined question.
In practice, the source has an intrinsic resistance > 0 and the wire has a resistance > 0 and if that is your question, Ohms law (or a voltmeter) and basic circuit theory will give you answers but I don't know exactly what you are asking currently.
