Electric circuits — practice question

The diagram illustrates a potential divider circuit. The temperature of the thermistor rises. What happens to the resistance of the thermistor, and what happens to the reading on the voltmeter?

  • Aresistance of thermistor decreases; voltmeter reading decreases
  • Bresistance of thermistor decreases; voltmeter reading increases
  • Cresistance of thermistor increases; voltmeter reading decreases
  • Dresistance of thermistor increases; voltmeter reading increases
