2 3W resistors of equal resistance in parallel or series = 1 6W resistor for series it will have twice the rated resistance of each unit, for parallel it will be half the rated resistance.
Power = Voltage * Current In series each unit takes half the voltage of the pair, in parallel each unit takes half the current....This assumes the two resistors are of equal value....If different the math for power ratings gets more complicated.
It may be useful to do some practice ohms law math, and network analysis math to gain a better understanding.
In other news that part that was low stock turned out to be NO-Stock...I had to call Mouser and ask about it for them to send me the rest of my order....Which apparently they were not going to ship till I asked...
