Re: voltage loss over long runs

Basically, you have +12 -> R1 -> load-> R2 -> ground.

But, R2 is sinking a lot of current, which is in essence ground, and not really resisting the current.

However, if you are saturating the wire, then "pushing" power to ground could result in voltage loss needed to push the power to ground.

Just some thoughts from a Math major, and not a EE major.
