Current Limiting
What is current limiting?
Current limiting is a protective technique used to restrict the maximum amount of electrical current that can flow through a circuit or component. It prevents damage to sensitive components like LEDs, ICs, or other devices that could be destroyed by excessive current flow. This is typically implemented using resistors, specialized current limiting circuits, or built-in protection features in power supplies and regulators. Current limiting is essential for safe circuit operation and component longevity in electronic designs.
