Conductance measures the ability of a material to allow the flow of electric current. This unit is crucial for understanding how easily electricity can move through various substances, from metals to semiconductors. Whether it’s the high conductance of copper wires or the low conductance of insulators, this category helps us quantify electrical properties that are essential for designing electrical circuits and systems. Conductance is inversely related to resistance, and understanding it is key to numerous applications in electronics and power systems.
