OK now that you appear to have two valid answers lets once again review what I had posted many post ago...
Now reading the above, you have the first two values needed, and should have an answer for me in regards to "........ Get this number, simple subtraction, got it? ........"
Post that answer and we move onto the next step...
I was going on but i got sleepy so i had to stop lol my meds made me sleepy, but now im back with the anwsers.
Ok lets begin.
The ps2 volts are DC 8.5 volts the source of volts, now minus the volts for the LED which is 3.5 volts.
Now, i get a number that = to 5. volts.
heres what you told me, i take that number 5. volts and i devided by the LED amps which i found out that is 20 amps = 0.25, something tells me that my next test will be finding out what the 0.25 means to my level of I Q, which is the world of electronics and the numbers with the dots and all those other ones in between.
What i am getting is this, we are deviding numbers backwords and not forword. so in the real world we take the big number and dvide that by the small. but in ohms law, the small number is first then the big number.
because the small number is the overall volts that the system is putting out on each part inside the pcb which is 5 volts.
