Fuses blow when excessive current--above the fuse's rating--is drawn by
one or more loads on its circuit; i.e. a short (slow-blow fuses allow a
momentary high draw before blowing, like a Healey's O/D circuit). If a
fuse has excessive resistance, it limits the current somewhat (like one
of its loads). Effectively, it becomes a resistor. Fuses don't--or
shouldn't--offer much resistance, excessive resistance usually comes
from its connector or housing.
