Q

What is the name of the semiconductor that decreases in resistance with an increase in temperature?

🔍 Key Concepts

• Semiconductor devices that change resistance with temperature • Difference between sensors (used for measuring temperature) and general components like resistors or diodes • How resistance vs. temperature behavior is used in control circuits

💭 Think About

• Which of these devices is specifically designed so its electrical resistance varies predictably with temperature and is commonly used as a temperature sensor? • Which options are general components that do NOT primarily act as temperature-sensitive resistive sensors? • Think about which term you’ve seen in contexts like thermostats, engine temperature monitoring, or electronic temperature controls.

✅ Before You Answer

• Identify which option is known as a temperature-sensitive resistor made from semiconductor material • Eliminate components whose main function is not to measure or respond to temperature (e.g., simple current control or voltage rectification) • Confirm in your memory which device’s resistance decreases as temperature increases (negative temperature coefficient)
