Specific resistivity (ρ) of a conductor depends mainly on:
ALength of conductor
BMaterial and temperature
CCross-sectional area
DCurrent flowing
Answer & Solution
Correct answer: B. Material and temperature
Resistivity ρ is a material property — set by atomic structure and electron mobility. Temperature affects it (most conductors: ρ increases with T). Length and area affect resistance R but not resistivity ρ.
