Parallel LED Current Limiting Resistor Calculator is an online electronic tool to measure How much total power dissipation would occur on the parallel connection of LEDs. The Light emitting diode often abbreviated as LED; is a PN junction solid state semi-conductor device emits light when current passing through it. It is important to calculate Current Limiting resistance and resistor wattage to avoid the LED from damaging. When it comes to online calculation, this Parallel LED Resistance Calculator can assist you to find out the values based on the input values of source voltage, voltage drop across LED, desired LED current and the number of LEDs Connected in Parallel
