🔍 Key Concepts

• Flexibility vs. strength differences between stranded and solid wire • How current-carrying capacity is actually determined (cross‑sectional area, insulation, temperature) • What skin effect is and whether normal DC or low‑frequency shipboard power makes it important in cable design

💭 Think About

• Ask yourself: Why would a shipboard cable need to bend around corners, through conduits, and move with vibration—how does wire construction help with that? • Consider what really changes when you take one solid conductor and replace it with several smaller ones of the same total metal area—does that automatically change current capacity or weight? • Think about typical ship electrical systems (often 50/60 Hz AC or DC). At those frequencies, is skin effect usually the main reason for using stranded wire in power cables?

✅ Before You Answer

• Verify which option clearly emphasizes mechanical properties (how the cable behaves physically when routed/handled) rather than just electrical theory. • Check whether any answer choice relies on skin effect as a primary reason—decide if that is realistic for normal shipboard power frequencies. • Eliminate choices that claim big changes in weight or conductivity when the total copper cross‑section remains the same.
