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