Final answer:
Current will be larger in a wire with a higher voltage, in accordance with Ohm's Law, which states that current is directly proportional to voltage for a given resistance.
Step-by-step explanation:
All other things being equal, current will be larger in a wire that has a larger value of voltage. The question relates to Ohm's Law, which states that current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. Given the formula I = V/R, it's clear that for a constant resistance, if you increase the voltage, you also increase the current. None of the other choices, such as resistance, length, or temperature, logically fit the scenario where 'all other things being equal,' the current would be larger.
