In the circuit diagram, a variable resistor $R$ is connected in parallel with the lower section of a potential divider. The resistance of $R$ rises. What effect does this have on the two voltmeter readings?
- A$V_1$ decreases, $V_2$ decreases
- B$V_1$ decreases, $V_2$ increases
- C$V_1$ increases, $V_2$ decreases
- D$V_1$ increases, $V_2$ increases
