Electrical Conductivity

Definition

Electrical conductivity is the measure of a material's ability to conduct an electric current. It describes how well electricity can flow through a substance, which is crucial for understanding various materials, including metals, semiconductors, and insulators. This property plays a significant role in applications ranging from electronic devices to energy transmission, and is especially important in the study of materials like quasicrystals, where unconventional structures can lead to unique conductive behaviors.
