Electric circuits — practice question

The diagram depicts a circuit in which a fixed resistor is connected in series with a thermistor and an ammeter. Which row indicates how a change in temperature affects the thermistor’s resistance and the current in the circuit?

  • Atemperature decreases, resistance of thermistor decreases, current in circuit increases
  • Btemperature decreases, resistance of thermistor increases, current in circuit decreases
  • Ctemperature increases, resistance of thermistor decreases, current in circuit decreases
  • Dtemperature increases, resistance of thermistor increases, current in circuit increases
