Voltage across resistor
Required Resistor Wattage


















LED Calculator(Shows required Resistor at specified voltage and current)
LED brilliance is shown for effect only..... typically a current of 16ma is sufficently bright





  Use Slider for desired Current
         100% = 20 ma



 NOTE: LED voltage is set at 1.8 VDC.  This calculation also treats the LED as an ideal device ( having no internal resistance)
