What is conductance?

Conductance is defined as the ability of a material to pass electrons, which reflects how easily electric current can flow through that material. Essentially, conductance is the reciprocal of resistance; a material with high conductance has low resistance and allows electric current to flow freely. This property is fundamental in understanding electrical circuits, as it determines how efficiently a circuit can operate when a voltage is applied.

In practical terms, materials with high conductance, such as metals, enable easier movement of electrons, leading to a higher current flow for a given voltage. Conversely, materials with low conductance, such as insulators, hinder the flow of electrons, resulting in lower currents. Thus, the concept of conductance is crucial for designing efficient electrical components and systems.
