The diagram represents a circuit that has a break between points P and Q. Four metal wires made of the same material are, one after another, joined between points P and Q in the circuit. The table lists the diameters and lengths of the wires. In which wire is the current greatest?
- Adiameter $0.10\,\text{mm}$, length $1.0\,\text{m}$
- Bdiameter $0.10\,\text{mm}$, length $2.0\,\text{m}$
- Cdiameter $0.20\,\text{mm}$, length $1.0\,\text{m}$
- Ddiameter $0.20\,\text{mm}$, length $2.0\,\text{m}$
