10 or 12 is the wire size, 2 or 3 the number of conductors. All Romex
type
cable has a ground which is not referenced as an "official: conductor.
10/3
cable has 3 10awg power carrying conductors and a ground. The 3 conductors
are white (neutral) Black and Red (hots) and is used in balanced 240/120
volt circuits (120 from each hot to neutral, 240 across the hots) 10/2
has
a white and black and is used in 120volt circuits only.

This is just patently incorrect. Perhaps it's a typo, but in matters like
this good proof reading becomes essential. 10/2 is not used in 120v
circuits only.
