The function of a circuit breaker is to prevent electrical overloads in a circuit. A circuit breaker is designed to automatically interrupt the flow of electricity when it detects an overload condition, which occurs when the electrical current exceeds the designated safe levels. This interruption helps to protect electrical circuits from damage due to overheating and prevents potential fires or other hazards that can result from excessive current.

By automatically disconnecting the circuit, a circuit breaker ensures that the electrical system remains safe and stable, allowing for effective management of electrical loads. It is an essential safety device found in homes and industrial installations, contributing to overall electrical safety and reliability. Other options such as restoring power, providing outlets, and storing energy do not accurately describe the primary purpose of a circuit breaker. While they are important functions within electrical systems, they are not directly associated with the core function of a circuit breaker.
