✌Answer✌
Resistance of a conductor depends on :
1. Length of the conductor (more the length, more the resistance)
2. Cross-sectional area of conductor (more the cross sectional area, less is the resistance)
3. Temperature of conductor (more the temperature, more is the resistance as conductors generally have positive temperature coefficient)
4. Nature of material of the conductor.

The factors at which the resistance may depend:
- The flow of electrons in the subatomic levels is the one that decides how conducting a material is and what resistance it has to offer.
- The resistance that is offered by different materials might different but this can be changeable depending on crosssectional area of the conducter used.
- The length of the materials has a role in the resistance variation, if length increases then the resistance increases.
Electric resistivity:
- Electrical resistivity is the quantifies in that how a given material strongly opposes the electric current flowing in it. And also known as "specific electrical resistance". Its SI unit is "ohm meter" (Ωm).
