Calculate LED Resistor

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

Calculate LED Resistor

LED-Voltage*: V
* Add the LED-voltages, if you are using more then on Led in series!
   +-  * infrared=1.5V
Voltage: V
Current: mA


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