C. They sense too much current.

D. They sense an overvoltage condition.



Answer :

GinnyAnswer

Final answer:

Circuit breakers trip due to sensing excessive current flow, preventing overheating. They function to protect against hazards like electrical shocks and utilize specialized methods for interrupting high-voltage electricity safely.


Explanation:

Circuit breakers trip because they sense too much current flowing through a circuit. When the current exceeds the rated limit, the circuit breaker automatically opens to prevent overheating and potential hazards.

Residual-current circuit breakers are designed to switch off the power supply when they detect a leakage of power, which could occur if someone touches a live wire, preventing potential electric shock accidents.

Large circuit breakers in power-distribution systems use specialized techniques like insulating gas and jets of gas to extinguish sparks that may occur when interrupting high-voltage electricity flow, ensuring safety and efficiency in power distribution.
