Wire wound resistor
#2

Wattage is always U-square over R.
You know the voltages at the taps of each section and each section's resstance, so the difference of the voltage between any two pins (or the same measured directly as voltage between pins) squared over its resistance will be your disipation, then use a factor of at least two.
