A cell with internal resistance $2.0\,\Omega$ and electromotive force (e.m.f.) $1.5\,\text{V}$ is connected to a resistor whose resistance is $3.0\,\Omega$. What is the potential difference across the $3.0\,\Omega$ resistor?
- A$1.5\,\text{V}$
- B$1.2\,\text{V}$
- C$0.9\,\text{V}$
- D$0.6\,\text{V}$
