A potential divider is made from resistors with resistance $R_1$ and $R_2$ joined in series across a source of potential difference $V_0$. The potential difference across $R_1$ is $V_{\text{out}}$. Which alterations to $R_1$ and $R_2$ would increase the value of $V_{\text{out}}$?
- A$R_1$ doubled, $R_2$ doubled
- B$R_1$ doubled, $R_2$ halved
- C$R_1$ halved, $R_2$ doubled
- D$R_1$ halved, $R_2$ halved
