Calculating the led resistor is made easy with this LED Resistor Calculator. Verify your work & save time with this free LED Resistor calculator.
Use this tool to calculate the resistance required to drive one or more series-connected LEDs from a voltage source at a specified current level.
LEDs are usually operated via a series resistor. The series resistor must be dimensioned in such a way that the supply voltage and the maximum permissible current are not exceeded. You can calculate the size of the resistor on this page.
