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