The formula for resistive wattage dissipation does not include "distance" in it.
The formula is i^2r (i squared times r) where i is current and r is resistance.
So 10 amps flowing through 2 ohms dissipates 200 watts, and it does not matter if the "2 ohms" is 1mm long or 1m long.
So what matters is the net resistance of that short distance, not the distance itself.
