How much resistance will astrotheme search WebJan 7, 2015 · Blue LEDs typically have a higher voltage drop, which means a lower resistor value. If you assume 5 volts applied and 3V across the LED, that leaves 2V across the resistor. If you want 20mA, that's 2V/0.02A = 100 Ohms. Thomas499 January 6, 2015, 5:05pm 3. I bought two starter packs so I have plenty of led's. WebMar 11, 2015 · LED Vf=3V. LED current = 1000mA. Power supply of 5V. R = (5-3)/1. R = 2 ohms. Now calculate for the resistors wattage rating.. W = I^2*R so 1x2 = 2Watts. then … astrotheme prince george WebJan 25, 2024 · 1. You can't get there from here. 3.3V is not enough the reliably light the green and blue parts. and the red part with only between 0.5 and 1.1V spare may give … astrotheme prince andrew WebMay 7, 2024 · That means the resistor in the series combo needs to drop (9 - (2*3)) = 3 volts, and the resistor on the lone LED needs to drop (9 - 3) = 6 volts. Current is continuous through a wire, so 15mA is the current. Using those values, you use Ohm's law which is very basic. This will calculate the values for the resistor: V = IR -> R = V/I.
