The diagram illustrates a circuit that includes a variable resistor linked to a variable power supply. The table gives the currents for different values of the potential difference (p.d.) and the resistance. What sequence do the currents follow, from the smallest to the largest?
- A$I_1 \rightarrow I_2 \rightarrow I_3$
- B$I_1 \rightarrow I_3 \rightarrow I_2$
- C$I_2 \rightarrow I_1 \rightarrow I_3$
- D$I_3 \rightarrow I_1 \rightarrow I_2$
