Circuit Breaker is a 'switch' that ___________ the flow of electricity at the first signs of an overload:

• A. Manually increases
• B. Automatically surges
• C. Manually shuts off
• D. Automatically shuts off

Answer: (D)

Circuit breakers are protective devices that respond automatically to electrical overloads or faults by opening the circuit and stopping the current. This automatic trip prevents overheating and reduces the risk of fire or damage. While you can manually switch off a breaker, the key function during an overload is the automatic shutdown. It does not intentionally surge current, and it isn’t about manually increasing flow.
