How does the current strength in a conductor depend on the voltage at the ends of the conductor?

According to Ohm’s law, the current I is directly proportional to the voltage U at the ends of the conductor and inversely proportional to the resistance of the conductor R.
I = U / R.
This means how many times the voltage U increases, and the current strength I.
How many times the voltage U decreases, so many times the current strength I.
