1 ohm, how many watts? or do i just ask for a 1 ohm resistor? I'm stupid. sorry.

thanks guys

Most of the common resistors out there can handle up to 0.5 watts. From the numbers Meduza posted, with a 1 ohm resistor, you are dissipating 659mW or 0.659 watts in the resistor. With a 2 ohm resistor, you are dissipating 515mW or 0.515 watts. With either resistor, you are over the 0.5 watt limit, which means possible meltdown of the resistor. You can either look for resistors which are rated for 1 watt or higher, or you can use several 0.5 watt resistors to dissipate the power. The formulas for series and parallel combinations of resistors are below.

Series: Equivelant resistance is the sum of the resistor values.

Parallel: Equivelant resistance is the inverse of the sum of the inverses of the resistances. (If R1, R2, R3 are resistor values, equivelant resistance is ((1/R1)+(1/R2)+(1/R3))^-1

Hope this helps
