What is electrical conductance?
Electrical conductance is a measure of the flow of electricity through an electrical component for a given potential difference. The SI unit of conductance is Siemens. It is the inverse of electrical resistance so that the conductance, G = 1/R, where R is resistance in ohms (hence a playful alternative name for the SI unit is the “mho”). Electrical conductance should not be confused with the related measure of conductance, which is a property of the material itself. Conductance is also connected to susceptance and admittance in AC (Alternating Current) circuits. Y= G + jB or G = Re(Y), Where Y= Admittance, j is the imaginary number and B is the Susceptance. When Kirchhoff’s voltage law is applied we find that the voltage is the sum of the voltages across each conductance: G = (G1.G2) / (G1+G2) In semiconductors the conductance of components such as diodes and transistors is usually evaluated for small signal conditions with appropriate bias so that operation is in the linear region of
