Hello,
Could someone please tell me the formula to calculate the maximum led's a power pack could handle? I have read myself into utter confusion and my brain hurts. Does it depend on wattage or ampage? I know it will need ohms law somewhere.
I have a 12volt, 3 amp power source.
I know i should only use 80% of it so as not to strain it. I will love you forever if you show me the maths clearly laid out (i'm rubbish at maths). Do i divide 3000 milliamps by 20 (the ampage of my leds). Then i read something about wattage is the key and have subsequently lost the page where that was.
Thanks if you help
