Electric Circuits: Analyzing Current Changes w/ Variable Potential Difference

[Twoacross]

Homework Statement

A source of variable potiential difference is attached across the ends of 1.0 m of resistance wire and the potiential difference across the wire is steadily increased. Describe how the current through the wire changes and provided that the temperature stays the same, what ratio is constant as the potiential difference across the wire increases?

The Attempt at a Solution

Im going over all my notes, and this seemed to be the part which i don't understand clearly. This not a question but more of an explanation we did in class. If someone could explain it, it be greatly appreciated, just the wording is kind of confusing for me

Thank you!

Really it's asking about Ohm's law, V=IR. If R is fixed, and you increase V, what has to happen to I?
