for this u must tell either current flowing through the resistor or potential drop across it
then by the formula , we can determine which is correct
power = I^2 X R = V^2 / R watts
I -----is current flowing through R = 12ohm
V-----is voltage drop across R
R -----resistance = 12 ohm

No answer is possible with the info provided. You have to specify a current through the resistor or a voltage applied across it.

Without knowing the voltage drop or current, your question is insoluble.
BTW, it's spelled watts, not walts.

Sorry, Hon, you need to provide either a voltage level or a current level. P=I^2R or P=V^2/R
