With six gauge wire the resistance of the coil will be close to 0.DHS Science said:Last night i went out and bought a pack of 2 resistors that allow 100 ohms and 10W. So if hook both of them up parallel in the line then i should be fine? Because if i do then the power will be divided evenly between the two resistors and will still only allow 10W thru in all, correct?
Power in resistor is E squared times R.
In this case 12^2 /100 = 1.4 watts.
The resistor does not limit watts.
It only provices resistance.
#6 wire should be able to handle about 30A to 40A without heating up too much.
Current in the coil is E/R.
Or in this case 12/50 = 0.24A
You may want to use smaller resistance value.
For 10W resistors 30 ohms is about as low as you want to go with a 12v source.
This provides a safety factor since the 10W rating is only for ideal conditions.
