A current limiting circuit is an electronic system designed to prevent excessive electrical current from flowing through a device or circuit. By automatically restricting the current to a safe, predetermined level, it protects sensitive components from damage due to overloads, short circuits, or faults. Current limiting circuits are commonly used in power supplies, battery chargers, and various electronic devices to enhance safety and reliability. They play a crucial role in preventing overheating, fires, and equipment failure by ensuring that the electrical current remains within safe limits.
