Yea, no luck. I am having no luck applying the formulas into anything I can understand.
I have approximately 19v power source to the board,,,
I have 4 each 5w, 13.5 volt bulbs, and so I THINK they are .3703 amps each,,,,,,,,
beyond that, I have no clue
These may be terrible choices for bulbs, and thats ok. I'm trying to figure out what resistor I would need to make them work, or, how to substitute say a more common bulb size like 12v .15ma and resistor combination to make this circuit stable. As you can tell I have zero training in the use of ohm's law. The formulas are easy enough to use, knowing which variables to use when, not so much.
I have a given feed, and need 4 light bulbs, in parallel,,,,,,,,, what is the formula to find the proper resistor when calculating various bulb choices, (Vots and watts, or ma)
