In the circuit shown, if we gradually increase the variable resistance $R_1$, the EMF decreases and the potential difference across the terminals of the source, and across $R_1$, how do they change? (from right to left) [Figure: Circuit with EMF source $\varepsilon$, internal resistance $r$, and two resistors $R_1$ (variable) and $R_2$ in series]
