What is the advantage of a current limiter?

1. Increases current flow efficiency

2. Can be manually reset

3. Will take overload for a short period

4. Reduces the need for multiple fuses

The correct answer is: Will take overload for a short period

A current limiter is a device that helps limit the amount of current flowing through a circuit, preventing overloading and damage to the circuit and connected devices. The other options listed do not accurately describe the advantage of a current limiter. Option A suggests that a current limiter increases current flow efficiency, which is incorrect as its purpose is to limit current flow. Option B implies that current limiters can be reset manually, which may be a feature of some current limiter designs but is not necessarily an advantage. Option D incorrectly states that a current limiter reduces the need for multiple fuses, as a current limiter typically works in conjunction with a fuse to provide overcurrent protection. Overall, the most correct answer is option C as it accurately describes the main advantage of a current limiter.
