What is the primary purpose of using circuit breakers?

The primary purpose of using circuit breakers is to protect circuits from overload and short circuits. Circuit breakers are designed to automatically interrupt the flow of electricity in the event of a fault, such as an overload that could cause wires to become too hot or a short circuit that could lead to fire hazards. By breaking the circuit in these situations, circuit breakers help to prevent damage to electrical appliances, reduce the risk of electrical fires, and ensure the safety of the electrical system as a whole.

The other options focus on aspects that are not the main function of a circuit breaker. While enhancing aesthetics or providing connection points might be concerns in electrical design, and minimizing resistance relates to efficiency in circuits, none of these objectives aligns with the crucial safety role that circuit breakers play in protecting electrical systems from potentially dangerous conditions.
