While taking photographs in Death Valley on a day when the temperature is 59.0°C, Bill Hiker finds that a certain voltage applied to a aluminum wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current does he register there if the temperature is -88.0°C? Assume that no change occurs in the wire's shape and size.

2. Relevant equations

I need to find the new current at a different temperature

3. The attempt at a solution

I used the equation Rf = Ri [1+alpha(Tf-Ti)

And was thinking that i would find Rf and then use ohm's law to find I for the final temperature. but i don't know what V is. or maybe i have to solve using another equation and then subtituing it in.
