is there a functional difference, other factors ie metal purity equal,
between 8-12-14 gauge wire having 10 strands and 25 strands ?
** Yes, stranded wire is far more flexible.
does covering each copper strand with aluminum coating increase
conductivity ?
** Aluminium wire is often coated in copper, not the other way around.
It improves conductivity and most importantly makes it possible to solder the ends.
Sometimes it is passed off as being pure copper to the unwary.
