LED Series Resistor Calculator
Online electrical calculator which helps to calculate the resistance of a LED resistor circuit using the Ohm's Law.
Calculate LED Resistance using Ohm's Law
Code to add this calci to your website
R = (Vs-Vd) / If
R = Resistance,
Vs = Supply Voltage,
Vd = Voltage Drop,
If = Forward Current
LED resistance calculation is made easier here using Ohm's Law Resistor calculator.
