LED calculator | LED resistor calculator

This page covers LED calculator. The LED resistor calculator is used to calculate LED series resistor in the LED circuit. This LED calculator takes source voltage, LED voltage and LED current as inputs and produces LED resistor and LED power as output values.

Example of LED calculator:
INPUTS : Vs = 5 volts, Vled = 0.5 volts, Iled = 5 mA
OUTPUTS: LED resistor (Rs) = 900 Ohm, LED Power =0.0025 Watts
