Unit of Specific Conductance |
|
Specific Conductance is the ability of a substance to conduct electricity. It is the reciprocal of specific resistance. Conductance means the flow of current through the liquid conductor. Specific conductance is defined as the conducting capacity of a solution of the dissolved electrolyte and the whole solution is being placed between two electrodes are 1 sq. cm and length 1 cm.
From (1) and (2)
⍴: Specific Resistance
l: length
A: Area of cross-section
R: resistance
Note:
When l = 1 cm
A= 1 cm2
Then ⍴=R
Hence,
Specific resistance (or resistivity) of a conductor can be defined as the resistance of the conductor having a length of 1 cm and a cross-section area of 1 cm2.

Unit of Area = cm2
Unit of length = cm
Unit of conductance = Ω-1
Unit of ? = cm-1 Ω-1
Also the unit of conductance = Ω-1 = Seimen
Then, Unit of (specific conductance) = Seimen cm-1
So, the unit of specific conductance is cm-1 Ω-1 or Seimen cm-1.
