Parallel LED Current Limiting Resistor Calculator

The Formulas

The formulas for calculating the parallel LED current limiting resistor value and its power dissipation are:

\[Resistor Value (R) = \frac{Supply Voltage - LED Forward Voltage}{Total LED Current}\] \[Power Dissipation (P) = (Supply Voltage - LED Forward Voltage) \times Total LED Current\] \[Total LED Current = LED Forward Current \times Number of LEDs\]
