Detailed Solution

According to Ohm's law, if the physical circumstances, like temperature, are constant, the current flowing through a wire is directly proportional to the potential difference applied across its ends.
V = IR
Where V is the potential difference R is resistance and I is current.
The current that flows through a wire is inversely proportional to its resistance, meaning that the higher the resistance, the lower the current, and vice versa.

Therefore, 'The potential difference applied across the ends of a wire is directly proportional to the current flowing through it.' is the correct response.
