Question 459Electricity & Electronics - QMED

The correct answer is D) provide different voltage values to operate various types of electrical equipment. Transformers on ships with AC generators are primarily used to provide different voltage values to power the various types of electrical equipment onboard. This allows the ship to efficiently utilize different voltage requirements for different systems, such as 440V for propulsion motors, 220V for lighting and small appliances, and 110V for specialized electronics. Transformers step up or step down the voltage as needed to match the requirements of each electrical system. The other answer choices are incorrect because they do not accurately describe the primary purpose of transformers on ships. Transformers are not used to increase or decrease power output to frequency controllers, nor are they used to directly change the line frequency value.
