Circuit breakers and fuses provide:

Circuit breakers and fuses provide:

• A. Protection from an overload of current
• B. Voltage regulation
• C. Current measurement
• D. Energy storage

Answer: (A)

Overcurrent protection. Circuit breakers and fuses are designed to interrupt current whenever it exceeds what the wiring and components can safely handle, preventing overheating, damage, and fire hazards. A fuse contains a thin conductor that melts when the current is too high, opening the circuit. A circuit breaker detects overloads (through thermal or magnetic sensing) and trips to physically disconnect the circuit, and it can be reset after the fault is resolved. They do not regulate voltage, do not measure current, and do not store energy.
