A potential divider is connected across the terminals of a 6.0 V supply. [circuit diagram: 6.0 V supply, 6.0 Ω resistor with voltmeter V1, variable resistor R with voltmeter V2] When R is adjusted to 6.0 Ω, the voltmeter readings V1 and V2 are equal. What happens to the readings when the resistance of R is then increased?

1. AV1 decreases, V2 decreases
2. BV1 decreases, V2 increases
3. CV1 increases, V2 decreases
4. DV1 increases, V2 increases
