Question 18Electricity & Electronics - Assistant Engineer

The correct answer is A) provide different voltage values to operate various types of electrical equipment. Transformers are used onboard ships with AC generators to step up or step down the voltage to the appropriate level required by different types of electrical equipment. This allows the ship to have multiple voltage systems (e.g., 440V, 220V, 110V) to power a variety of equipment, from large motors to smaller appliances. The other options are incorrect because transformers are not primarily used to decrease power output (B), change line frequency (C), or increase power output (D). Those functions are typically handled by other electrical components in the ship's power system.
