List-II (Symbol)

(A) Resistance

(III) $R$

(B) Specific resistance

(IV) $ρ$

(C) molar conductivity

  • (A) Resistance: This property represents the opposition to the flow of current. It is universally denoted by the symbol $R$.
    • Match: (A)-(III)
  • (B) Specific resistance (Resistivity): This is the resistance of a conductor of unit length and unit area of cross-section. It is denoted by the Greek letter $\rho$ (rho).
    • Match: (B)-(IV)
  • (C) Molar conductivity: This is the conducting power of all the ions produced by dissolving one mole of an electrolyte in solution. It is denoted by the symbol $\Lambda_m$ (lambda).
    • Match: (C)-(II)
  • (D) Specific conductance (Conductivity): This is the reciprocal of specific resistance. It is denoted by the Greek letter $\kappa$ (kappa).
    • Match: (D)-(I)
