🔍 Key Concepts

• Carbon resistor behavior with temperature (how heat affects resistance value over time) • Component reliability (what happens to reliability when a part is stressed beyond its rated temperature) • Manufacturer ratings and cooling requirements for electrical components

💭 Think About

• Think about what happens inside a resistor when it operates hotter than its design temperature for a long time. • Ask yourself whether excessive heat generally makes electronic components more trustworthy or less trustworthy over time. • Consider whether it is realistic for any resistor to always keep the exact same ohmic value under thermal stress.

✅ Before You Answer

• Check how temperature affects resistance value and tolerance drift in carbon resistors. • Verify what happens to a component’s failure rate when it is run hotter than its rated temperature. • Eliminate any option that implies improved performance or no change under overheating conditions.
