Nettet5 (System Voltage) = 2.4 (LED 1) + 2.4 (LED 2) + Resistor. 5 = 4.8 + Resistor. Resistor = 5 - 4.8. Resistor = 0.2. So there is .2V across the resistor! This is a simplified example … NettetThere is a you tube video, but it doesn't show much. He took a red led and connected it to the two wires. He applied a 100 ohm resistor inline and the indicator lit brightly in "stereo" but still glowed when in mono but not as brightly. He then said he placed another 100ohm resistor" across the LED. It worked perfectly. But, I couldn't see clearly.

NettetLEDs (Light Emitting Diodes) are semiconductor light sources that combine a P-type semiconductor (larger hole concentration) with an N-type semiconductor (larger electron concentration). Applying a sufficient forward voltage will cause the electrons and holes to recombine at the P-N junction, releasing energy in the form of light. NettetSee also LED Lighting and Resistors for a generic example. If you have two LEDs that will be controlled by the same function the LEDs can be wired in series and share the same resistor.
