Reality check ...........

If two lengths of resistance wire are in parallel but not in intimate
contact, they will be as paralleled resistors. But what if they are in
contact, eg twisted together ? That make a large number of
paralleled segments in series wouldn't it ?

Making some low-value sense resistors with Cuprothal wire, which
is 6 ohms/metre. If I parallel 4 strands (=> 1.5R/m) then that's 40mm
to make a 60mR resistor, rather than 10mm of the single strand. I'd
rather work with 40mm than 10mm
