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