Hello again.
I am wiring up 10 red (2.0 voltage drop)LEDs and 10 green(3.0 voltage drop) LEDs on the same circuit. The battery voltage is 3.6. Everything is in parallel. Do I use the calculator that says 3.6 volts, 3 voltage drop, 20 ma, 10 LEDs and find 30 ohm resistors on each LED (http://ledcalc.com/). and then do the same for the red leds that says 82 ohms. So do I put 10 30 hnm and 10 82 ohm resistors with their respective diodes? Or do i have do compensate that there are really 20 LEDs in parallel of of the 3,.6 volt battery.Ii can find many calculators but none use different voltage drops. Cam you help me?
Thanks. Dennis
