5054Resistance
The resistance of a metal wire depends on its length and on its cross-sectional area. What are the relationships for the resistance of the wire?
- Aresistance and length: direct proportion; resistance and cross-sectional area: direct proportion
- Bresistance and length: direct proportion; resistance and cross-sectional area: inverse proportion
- Cresistance and length: inverse proportion; resistance and cross-sectional area: direct proportion
- Dresistance and length: inverse proportion; resistance and cross-sectional area: inverse proportion
