Topic: Electronic Devices

A Sensistor exhibits the following characteristics

  • A. Either increase or decrease in resistance value with increase in temperature based on the material type used in the thermistor
  • B. Always increase in resistance value with increase in temperature
  • C. Always decrease in resistance value with increase in temperature.
  • D. No change in resistance value with temperature.

Answer: B. Always increase in resistance value with increase in temperature

Explanation: A sensistor is a heavily doped semiconductor resistor whose resistance changes with temperature. It has a positive temperature coefficient, meaning its resistance always increases exponentially with an increase in temperature.
