28 Σεπ 2024 · LED Resistor Formula. R = (V-Vf)/I. Example Calculation. The data sheet for a diode can be used to find its forward voltage and current. From the diode current voltage plot below Vf = 2 V and we use I = 5 mA
Calculator and formulas for calculating the LED series resistor. LEDs are usually operated via a series resistor. The series resistor must be dimensioned in such a way that the supply voltage and the maximum permissible current are not exceeded. You can calculate the size of the resistor on this page. LED resistor calculator.
28 Σεπ 2024 · This calculator finds the series resistor value to be used with an LED and a +12 Volt supply. This resistor limits current into the diode and is required for proper operation. It also provides the power dissipation in the resistor – an important number for resistor selection.
With this online tool, you can easily calculate the current-limiting resistor for one or more LEDs, both in series and in parallel. Simply input the number of LEDs, the supply voltage, LED forward voltage, and LED current.
3 Οκτ 2024 · Calculation Formula. The LED resistor value is determined using Ohm's law, with the formula: \ [ R = \frac {V_s - V_l} {I_L} \] where: \ (R\) is the resistance (in ohms, Ω), \ (V_s\) is the voltage of the source (in volts, V), \ (V_l\) is the voltage drop across the LED (in volts, V), \ (I_L\) is the current through the LED (in amperes, A).
Calculate resistor values for LEDs using this simple calculator. Enter any three known values and press Calculate to solve for the others.
