Current limiting refers to the practice of restricting the flow of electrical current in a circuit to prevent damage or excessive current from affecting circuit components. This is particularly important in protecting sensitive devices, ensuring that they do not receive more current than they can handle, which could lead to overheating or failure.

In many cases, current limiting is implemented through various means, such as circuit design, the use of resistors, fuses, or current-limiting diodes, to manage the flow of electricity effectively. By controlling the amount of current that can pass through the circuit, engineers can maintain safe operating conditions and enhance the reliability of the electronic components involved.

Understanding the concept of current limiting is crucial in designing and troubleshooting electrical circuits, as it plays a fundamental role in ensuring the safety and longevity of electrical devices.
