🔍 Key Concepts

• Relationship between temperature and resistance in conductors (like metals) • Difference between conductors (metals like copper) and insulators/semiconductors • Meaning of the term predictable in electrical characteristics

💭 Think About

• For most metals used as conductors, think about whether electrons move more easily or less easily as temperature rises. • Ask yourself: in electrical systems on a vessel, do we usually have to compensate for temperature changes when calculating resistance in metal wires? • Consider: if engineers use copper wiring in many standardized electrical formulas, does that suggest its resistance behavior with temperature is random or well-characterized?

✅ Before You Answer

• Verify whether copper is a good electrical conductor and how heat affects electron collisions in a metal. • Check if standard electrical formulas (like Ohm’s law tables or wire charts) assume resistance is constant or changes with known temperature coefficients. • Decide whether the behavior with temperature is predictable or unpredictable, and whether it tends to go up or down for metals.
