5054Action and use of circuit components
A resistor of constant resistance and a thermistor are connected in series with a battery. A voltmeter is connected in parallel with the resistor. The temperature falls. What are the correct changes?
- 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
