The LED Series Resistor Calculator is a useful tool used to determine the appropriate value of a resistor that needs to be placed in series with an LED (Light Emitting Diode). When an LED is connected directly to a power source without a resistor, it can draw excessive current and potentially get damaged or burn out.
This calculator helps avoid such issues by allowing users to input certain parameters such as the LED forward voltage (Vf), the desired operating current (If), and the power supply voltage (Vcc). By using these values, the calculator calculates the optimal resistance value (R) to be used in series with the LED.
The LED Series Resistor Calculator employs Ohm's Law (V = IR) to determine the resistance. It takes into account...
