In a circuit there are a cell, two resistors with resistances $R_1$ and $R_2$, and a variable resistor $X$. The cell is assumed to have negligible internal resistance. $V_1$ denotes the potential difference across the resistor of resistance $R_1$. $I_2$ denotes the current through the resistor of resistance $R_2$. The resistance of $X$ is decreased. What effect does this have on $V_1$ and $I_2$?
- A$V_1$ decreases; $I_2$ decreases
- B$V_1$ decreases; $I_2$ increases
- C$V_1$ increases; $I_2$ decreases
- D$V_1$ increases; $I_2$ increases
