Two 5-Ohm 5Watt resistors in series equals 10-ohms @ 5 Watts. The resistance adds in series & divides when parallel, the wattage only adds when parallel.

If they're of equal value, the wattage is additive in both series or parallel.

It gets messy when they're of unequal value, higher resistance consumes more power in series, lower resistance consumes more in parallel, but you can't just add up the wattages with unequal values.

Two 5-ohm 5-watt resistors in series = 10 ohms at 10 watts.

Two 5-ohm 5-watt resistors in parallel = 2.5 ohms at 10 watts.
