Led Current Limiting Resistor Calculator. Current limiting resistor calculator for leds. To use the calculator enter any three known values and press calculate to solve for the others.
Led resistor calculator a current limiting resistor sometimes called a load resistor or series resistor connects in series with a light emitting diode led so that there is a correct forward voltage drop across it. Superbright leds can go from 30ma up to several amps. This calculator is based on the ohms law calculator but takes into consideration the voltage drop from the led.
Our led calculator will help you determine the value of the current limiting series resistor when driving a single or an array of low current leds.
3 0 3 5 volts led current. 3 0 3 5 volts led current. Our led calculator will help you determine the value of the current limiting series resistor when driving a single or an array of low current leds. The current through the circuit is constant so iled is also the current through the resistor.
