The electrical properties and their respective SI units are given below. Identify the wrongly matched pair:-

Options

A. Electrical property-Specific conductance, SI-unit-`Sm^(-1)`
B. Electrical property-conductance, SI Unit-S
C. Electrical property-Equivalent Conductance, S `m^(2)` `"(gm equiv)"^(-1)`
D. Electrical property-Cell constant, SI unit-m

Answer

D

Explanation

Cell constant=1/a
Unit=m//`m^(2)=m^(-1)`
