Maximum resistance and power for LED

[QUOTE="gneill, post: 4981112, member: 293536"] Actually, the drop across the resistance will be less than 12 V. Remember V2 that you calculated before? The LED will exhibit an almost constant voltage drop due to its junction potential. LED's typically have a drop in the neighborhood of 2 or 3 V (depends upon the details of the construction and materials of the LED). So you'll want to work that into your figuring. I'm still unsure how to select a maximum resistance without knowing something else about the LED (like a minimum current that will produce visible illumination for the application at hand). [/QUOTE]
