Abbreviated with the capital letter K or the Greek letter ρ (rho), specific resistance is also called ?

• A. Inductance
• B. Load value
• C. Resistivity
• D. Ohms

Answer: (C)

Specific resistance is resistivity, the intrinsic property of a material that measures how strongly it opposes current, independent of the piece’s shape. It’s denoted by ρ (rho), and you may also see a capital K used in some contexts as an alternative symbol. The key relationship is R = ρ L / A, which shows why resistivity is intrinsic: resistance scales with length and inversely with cross-sectional area, but resistivity itself depends only on the material and temperature. That’s why resistivity is the best answer. Ohms is the unit of resistance, not the material property, and inductance or a load value describe different concepts in circuits.
