Hook it up to a variable DC supply. Turn up the supply slowly until the resistor goes up in smoke. Use Ohms law (P=(VxV)/R) to get the power rating.
Of course, that assumes you have one to burn :>)

Need help finding out the Watt Value of a resistor
Dear Technichians Fellows,
I need help figuring out the WATT value of a resistor.
It's 15mm (1.5cm) long, baby blue in color.
Looks like a 1 WATT but I have had 3 WATT ones in the same size, therefore I really dont want to take chances guessing.
I have the picture of the resistor if you guys need to take a look at it.
I got the OHM VALUE figured out, all I need is to find out if this resistor is 1W 3W or 5W.
Thanks a million!
Best,
KW
