22 Απρ 2020 · What is Conductance? Conductance, or electrical conductance, measures a material’s ability to conduct electricity, essentially showing how easily an electrical current can flow through it. It is the opposite of electrical resistance, mathematically expressed as 1/R.
Conductance is a measure of how easily an electrical current can flow through a material and is expressed in units called siemens (S). It is calculated by taking the reciprocal of resistance, so a higher conductance value indicates a lower resistance and better conductivity.
The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction.

Electrical conductance, G, is the reciprocal of resistance (R): G = 1 R G = 1 R. Electrical conductance measures how easily electricity flows through electrical components for a given voltage difference. The SI unit of conductance is siemens (the older unit was the mho).
Conductance is essentially a property found in good conductors of electricity, like aluminum and copper. Atoms and molecules in metals like these are in a state of random motion, which causes the electrons in the outer shells to move out of orbit and become free electrons.
Conductance, like resistance, is a property of devices. Specifically: Conductance \(G\) (\(\Omega^{-1}\) or \(S\)) is the reciprocal of resistance \(R\). Therefore, conductance depends on both the conductivity of the materials used in the device, as well as the geometry of the device.
