A battery with electromotive force (e.m.f.) $10\,\text{V}$ and internal resistance $5.0\,\Omega$ is attached to a $5.0\,\Omega$ load resistor. What change is observed when the $5.0\,\Omega$ load resistor is substituted by a $50\,\Omega$ load resistor?
- AThe current in the circuit increases.
- BThe potential difference across the load resistor increases.
- CThe power dissipated in the internal resistance of the battery increases.
- DThe total power dissipated in the circuit increases.
