I only have 1/4 Watt resistors in my Sparkfun kit, so....

I have 10 ohm ones, so if I put two in parallel I'll get 5 ohms and a slightly higher nominal current than suggested, viz 300mA.

The power will be 1.5V x .3A = 450mW.... and two 1/4W resistors in parallel will each be able to handle their share of that.

(EDIT: Alternatively a 10 ohm by itself would draw a current of 1.5 / 10 = 150mA for less of a test, but the power's just on the money for a 1/4 ohm resistor at 1.5 x .15 = 225mW)
