🔍 Key Concepts

• Electrical resistance vs. conductivity and how they relate to heat and power loss in cables • Material properties of copper vs. aluminum (weight, strength, resistance to corrosion) • Why regulations care about low resistance and reliable current-carrying capacity in shipboard wiring

💭 Think About

• Ask yourself: For the same size wire, which metal lets electricity flow more easily (has lower resistance) and therefore wastes less energy as heat? • Think about which property is more important for ship safety: lighter weight metal or lower electrical resistance? • Look carefully at each choice: does it correctly state the relationship between copper and aluminum in terms of resistance/conductivity and weight?

✅ Before You Answer

• Confirm which metal actually has lower resistance / higher conductivity: copper or aluminum? • Verify which metal is heavier for the same volume: copper or aluminum? • Eliminate any options that claim facts you know are backwards about resistance or conductivity.
