Combining a 10k/3w and a 47k/2w in parallel will produce a resistance of 8.2k.
But what about the wattage rating?
Does it remain at 3w?
Does it increase to 5w?
If the rating increases: Is there a disadvantage to this when using this combo as a power resistor?
Resistors in Parallel = wattage?

Re: Resistors in Parallel = wattage?
In parallel, it is V that is equal for all.
P can be computed using (V^2)/R in each resistor. You *have* to verify P for every resistor you connect and *each* resistor must respect its *own power rating* at all times.
