70% to pass

Electric generators can be protected against overload _______________.

A by using heavy wire
B with fuses or circuit breakers
C with a governor on the engine
D with switches
AI Explanation

The correct answer is B) with fuses or circuit breakers. Electric generators need to be protected against overload to prevent damage to the generator and connected electrical systems. Fuses and circuit breakers are the proper devices to provide this protection. They are designed to automatically disconnect the generator from the load if the current exceeds a safe level, preventing overheating and potential fire hazards. The other options are not appropriate for overload protection. Heavy wire alone does not provide overload protection. A governor on the engine controls the generator's speed, but does not protect against electrical overload. Switches can be used to manually disconnect the generator, but do not provide automatic overload protection.
