Thanks man, I will use that.

 

Hey Hemi,
Radioshack doesnt have 2, 3 or variations. Only 1, 10, 100, 1k. So I was thinking on runing it in series 3 1ohm resistors to make it 3ohms. Will that work? Let me know. Thanks.

 

No, they won't have some resistors.
Resistors are sold in what they call "prefered values".
You have to make up combinations of resistors in either parallel or series to make up what value you require.
Use ohms law, to figure out how to string them together to make up a specific value.
Hope this helps?

In series resistors add. Here is the formula for resistors in parallel 1/ (1/r1+1/r2+1/r3) use the 1/x function on your scientific calc. Remember the answer will always belower than yourlowest resistor.

 

So if I want 3ohms, I would add 3 1ohms in series, n'est pas?
Why would I want parallel, that would not give me 3 ohms.

 

Well you said you read between 3.5 and 4 ohms so i dont know if 3 will do it. Try it, it works great, if not add a resistor. Just figured it was a usefull formula for future led replacements.

 

Thanksman. I will try it and let you know.

 

OK. I went to Radio Shack where their unknowledgeable people gave the deer at headlights look. I asked them for 1ohm resistors, they showed me these bricks that said 10 watt 1ohm resistors. I told them what I was planning on doing and how does the 10 watt come into play, they did not know. They told me to go to an alarm shop and ask there. I went to the 12volt and tried the ohm's law calculators, but I am as lost as Bush in a Mensa meeting.
Can I just use the 10ohm 1/4watt resistor and call it a day?
Thanks ahead.

 

Nah...............no can do I'm afraid.
You need the correct wattage resistor to handle the current draw of the ballasts or whatever your connecting up.
If you don't have the correct wattage reistors, they will burn up and be a potential scource of a fire.
Use this link to work out what wattage rating you will need for your circuit.

Don't forget, you must use the correct wattage resistor to make sure you don't create a potential fire hazzard.
Also, when you do fit the correct resistor rating, make sure that they are thermally insulated or cannot touch and burn something, so they can't pass on the heat they will produce and set it on fire.
A 10 watt resistor will, and does, get very hot!
Hope this helps you.
