Calculate LED Resistor



Please check LED-Voltage. This voltage can be different depending of type LED!


LED-Voltage*: V
* Add the LED-voltages, if you are using more then on Led in series!
   +-  * infrared=1.5V
     red=1.6V
     green=2.1V
     yellow=2.2V
     blue=2.9V
     white=4.0V
Voltage: V
Current: mA

Calculations:
Voltage to distroy: V
Resistor: Ohm
Current: mA
Energy dissipation: mW
Ω,
Resistor = Ω parallel Ω = Error = %
