What is conductance?


Open in App
Solution

Conductance

  • The ease with which electrons can pass in a conductor is measured by conductance.
  • Most analyses include specific conductance, which was calculated using a conductance bridge and a standard potassium chloride solution as a reference.
  • The tendency of an aqueous solution to convey an electric current is expressed numerically as conductivity.
  • Conductance (G) is an expression of how easily an ion flows across a membrane, either through active pumps placed in the membrane of ion channels, or when specific ion channels open.
  • The movement of ions conducts electricity through an electrolytic solution. In general, the conductance increases as the number of ions in the solution increases.
  • Conductance is the reciprocal of Resistance.
  • G=1R;
  • G = Conductance and R = Resistance
  • Unit for conductance is Siemens or ohm-1.

Factors affecting Conductance

  • The attraction between the ions
  • Solubility
  • Temperature
  • Viscosity
