🔍 Key Concepts

• Dissimilar metals and how they behave when joined and heated • The basic purpose and operation of a thermocouple in temperature measurement • How transistors and solenoids work and what they are typically used for

💭 Think About

• Which device is commonly used to measure temperature by producing a small voltage when heated? • Do transistors or solenoids normally rely on two different metals joined together to generate a current from heat? • Which of these options is specifically defined as two dissimilar metals joined at one end to sense temperature?

✅ Before You Answer

• Identify which device is based on two different metals joined together • Check which option is used specifically for temperature sensing or measurement rather than switching or producing motion • Eliminate any devices that are primarily electronic switches (transistors) or electromagnets (solenoids)
