Conductance measures the ease of electric current flow, being the reciprocal of resistance, and is represented by the symbol 'g' with units in siemens. It is related to Ohm's law, which connects current, voltage, and resistance, and can be expressed as current equals voltage times conductance. There are different types of conductance, including equivalent, specific, and molar conductance, influenced by factors such as material properties and temperature.

3. Conductance
• Conductance is a measure of the ease with which electric
current flows through a material.
• It is the reciprocal of electrical resistance.
• The higher the conductance, the easier it is for electricity to
pass through the material.
• Conductance is essential in various fields such as
electronics, physics, and chemistry.

4. Symbol and formula of
conductance
• Symbol: G
• Formula : G=1R
(Where R is the electrical resistance in ohms
(Ω).
• Unit : Siemens (S)
1 Siemens (S) = 1mho
1S = 1 Ω -1

5. Difference between
• Conductance:
The ease with which electric
current passes through a
material.
Symbol: G
Unit : Siemens (S)
• Conductivity:
Intrinsic property of a material
describing its ability to conduct
electricity.
Symbol = σ
Unit = S/m (Siemens per meter)

6. Ohm law
Ohm's Law and conductance are closely related concepts in the field of electrical circuits
and conductivity.
Ohm's Law states that the electric current (I) flowing through a conductor between two points
is directly proportional to the voltage (V) across the two points, and inversely proportional to
the resistance (R) of the conductor. Mathematically, Ohm's Law is expressed as:
V = I . 𝑅 or I = V R ----------------- 1
as Conductance is G = 1R which can be written as R = 1G------------------2
combine eq 1 and 2 we get :
I = V . G
This equation shows that the current (I)lowing through a conductor is directly proportional to
the voltage(V) and the conductance (G) of the conductor.

7. Types of conductance
Equivalent conductance:
The conductance of all the ions produced from 1g equivalent of electrolyte dissolved in
Vcm3 of the solution when the distance between the electrode is 1cm and area is large calle
d as equivalent conductance. The symbol for equivalent conductance is Λ . Its unit is Ω-1 cm2
(g)
Specific Conductance:
The conductance of unit volume of a cell is called specific conductance.The unit of
specific conductance is Ω-1 m . The symbol used to represent specific conductance is K

8. Types of conductance
Molar conductance :
It is the conductivity of the solution produced by the conductance of all the ions from
one mole of electrolyte dissolved in Vcm3 of the solution is called as molar
conductance. The unit of molar conductivity is ohm-1 cm2 .mol-1 .
It is denoted by the symbol Λ m

9. Factors effect conductance
• Material
• Temperature
• Length and Cross-Sectional Area
• Presence of Magnetic Fields

• Pressure and Strain
• Presence of Free Electrons or Charge Carriers

10. •Conductance Meter:
Measures direct current (DC) or alternating
current (AC) conductance.
•Conductance Bridge:

standard.
