    Resistor Calculation Formula (R)

    The difference between the output high voltage (Voh) and the LED voltage (Vled) divided by the current flowing through the LED (Iled). It represents the resistance of the current limiting resistor in an electronic circuit using an LED.

    Resistor Value Calculation

    The calculated resistor value for an LED using a specific voltage drop and current.

    Voh

    The high output voltage of a circuit, typically measured in volts (V).

    Vled

    The voltage drop across the LED, typically measured in volts (V).
