The diagram represents a circuit that includes two resistors with resistances $1.0\,\Omega$ and $2.0\,\Omega$. A voltmeter is attached across the $1.0\,\Omega$ resistor by joining P to X. The voltmeter reads $6.0\,\text{V}$. P is then shifted to point Y in the circuit. What will the voltmeter now read?
- A$3.0\,\text{V}$
- B$6.0\,\text{V}$
- C$12\,\text{V}$
- D$18\,\text{V}$
