A voltmeter is connected into a circuit with the polarity shown. The sliding contact is moved to end P of the potentiometer and then to end Q. What are the two readings of the voltmeter?

1. Asliding contact at end P: 0 V; sliding contact at end Q: 3 V
2. Bsliding contact at end P: 0 V; sliding contact at end Q: 6 V
3. Csliding contact at end P: 3 V; sliding contact at end Q: 3 V
4. Dsliding contact at end P: 3 V; sliding contact at end Q: 6 V
