SUMMARY

The purpose of placing a limiting resistor in front of an LED is to control the current flowing through the LED, thereby preventing damage due to excessive current. The resistor increases the total resistance in the circuit, ensuring that the LED operates within its specified current range. This practice is essential for maintaining the longevity and functionality of the LED.
