LED Current Limiting Resistor Calculator





Output of Series LED Resistance Calculation

The Series LED Current Limiting Resistor Calculator to measure How much total power dissipation would occur on the series connection of LEDs.

For example, when Vin is 10 volt, Voltage Drop Across LEd is 1 volt, the LED Current you desired is 5 mA, then Limiting Resistor will be 1800 Ohms, Calculated Resistor Wattage is 0.045 Watts.
