Electric circuits — practice question

The circuit diagram displays a fixed resistor R and a thermistor T in a potential divider circuit. $V_R$ and $V_T$ represent the potential differences across R and T respectively. What happens to $V_R$ and $V_T$ when the thermistor’s temperature decreases?

  • A$V_R$ decreases, $V_T$ increases
  • B$V_R$ increases, $V_T$ decreases
  • C$V_R$ stays the same, $V_T$ decreases
  • D$V_R$ stays the same, $V_T$ increases
