What is the purpose of a current-limiting resistor?
2 Answers
A current-limiting resistor is used to prevent excessive current from flowing through a component or circuit. It’s essential in protecting sensitive components, such as LEDs, from damage caused by too much current. By adding a resistor in series with the component, you can control the amount of current that flows through it, ensuring it operates within its safe limits. The resistor's value is chosen based on the desired current and the voltage applied to the circuit.

By placing a resistor in series with a device, you control the amount of current that can pass through it, protecting sensitive components from damage due to high current. The resistor's value is chosen based on Ohm's Law to ensure the current remains within safe limits for the circuit. Do you have a specific circuit or component you're working with?
