A student produces four resistors from separate lengths of wire. These wires have different diameters and different lengths. Each wire is made from the same material. Which wire would produce the resistor with the greatest resistance?
- Adiameter $0.8\,\text{mm}$, length $10\,\text{cm}$
- Bdiameter $0.8\,\text{mm}$, length $17\,\text{cm}$
- Cdiameter $2.0\,\text{mm}$, length $10\,\text{cm}$
- Ddiameter $2.0\,\text{mm}$, length $17\,\text{cm}$
