🔍 Key Concepts

• High voltage systems vs low voltage systems on ships • Typical advantages of high voltage (HV) distribution (size, weight, current) • The impact of safety procedures and insulation requirements at higher voltages

💭 Think About

• Look at each option and ask: does this make the system more efficient or more compact, or does it create extra burden/risk? • Which features of high voltage systems are usually advertised as reasons to use them on large ships? • For the remaining choice, think about what extra precautions and training are required when voltage levels increase.

✅ Before You Answer

• Identify which options describe benefits/advantages (smaller size, lower current, lower weight). • Identify which option describes an operational or safety burden rather than a benefit. • Before selecting, confirm that the choice you pick would make engineers and crew say, "this is harder/more demanding" rather than "this is better/more efficient."
