A cell with electromotive force (e.m.f.) $E$ and negligible internal resistance is placed in a circuit, as illustrated. The voltmeter, which has a very high resistance, measures a potential difference $V_{out}$. What is the value of the ratio $\dfrac{V_{out}}{E}$?
- A$\frac{1}{6}$
- B$\frac{1}{3}$
- C$\frac{1}{2}$
- D$\frac{2}{3}$
