What is the function of a circuit breaker?

• A. To amplify electrical signals
• B. To protect an electrical circuit from damage caused by overload or short circuit
• C. To convert voltage levels
• D. To store electrical energy

Answer: (B)

The primary function of a circuit breaker is to protect an electrical circuit from damage that can occur due to overloads or short circuits. When the current flowing through a circuit exceeds a predetermined level, the circuit breaker detects this excessive flow and interrupts the circuit, stopping the flow of electricity. This action prevents potential hazards, such as overheating, fires, and damage to appliances or wiring. In contrast to amplifying electrical signals, converting voltage levels, or storing electrical energy, which are functions associated with other electrical devices (such as amplifiers, transformers, or capacitors), the circuit breaker is specifically designed for safety and protection within electrical systems. Its role is crucial in maintaining the integrity and safety of the electrical infrastructure, ensuring that both people and equipment are safeguarded from the dangers posed by excessive current.
