The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R. Ohm's Law is given by: V = I R where V is the potential difference between two points which include a resistance R.
V ∞ I
V ∞ R
V=IR
V ∞ I
V ∞ R

The electric current flows through two ends of conductor is directly proportional to the voltage across the two points and is inversely proportional to the resistance.
