Jerry framed the question very nicely.

The logic seems simple. More force is required when resistance to change
is higher. When current is very small despite high force, it must be due
to high resistance.

Resistance proportional to force (volts) and inversely proportional to
current (amps) seems perfectly logical to me. R=E/I
