The graph shows the voltage-current relationship for two resistance wires P and Q. Both wires are made of the same material and have the same length. However, their resistances and cross-sectional areas are not the same. Which wire has the larger resistance, and which wire has the greater cross-sectional area?
- Agreater resistance P, larger cross-sectional area P
- Bgreater resistance P, larger cross-sectional area Q
- Cgreater resistance Q, larger cross-sectional area P
- Dgreater resistance Q, larger cross-sectional area Q
