In a transistor, as heat increases, leakage currents 

  1. decrease
  2. increase
  3. are not affected
  4. are equal to forward currents 

The primary advantage of a thermistor used as a thermal transducer is its 

  1. linearity
  2. ability to withstand high temperatures
  3. fast response to temperature changes
  4. ability to convert thermal energy directly to a voltage, eliminating the need for an  external voltage source
