A, B, and C
The resistance of a conductor of length, l and cross-sectional area, A is given by R=ρlA where ρ is the resistivity. Factors affecting the resistance of a conductor are:
- Length of the conductor - Resistance is directly proportional to the length of the conductor.
- Area of the cross-section of the conductor - Resistance is inversely proportional to the cross section area of the conductor.
- Material of the conductor - Resistance depends on the material of conductor. It is quantified by resistivity. Resistance is directly proportional to resistivity.
