🔍 Key Concepts

• Seebeck effect and how it relates to temperature measurement • Difference between voltage-generating sensors and resistance-changing sensors • Role of hot and cold (reference) junctions in certain temperature systems

💭 Think About

• Which device in the list works by joining two dissimilar metals and producing a small voltage when there is a temperature difference? • Which devices in the options primarily change resistance instead of directly generating a voltage? • Think about which sensor type specifically requires both a measuring (hot) junction and a reference (cold) junction.

✅ Before You Answer

• Identify which option uses two dissimilar metals joined together • Confirm which options are based on resistance change rather than direct voltage generation • Verify which system explicitly mentions a hot junction and a cold (reference) junction in its operating principle
