vezetképességét
Vezetőképesség refers to the ability of a material to conduct electric current. This property is dependent on the presence and mobility of charge carriers within the material. In conductive materials, such as metals, electrons are readily available and can move freely when an electric field is applied, allowing for efficient current flow. This high degree of conductivity is why metals are extensively used in electrical wiring and electronic components.
In contrast, insulating materials possess very few free charge carriers or their charge carriers are tightly
The quantitative measure of vezetőképesség is electrical conductivity, often denoted by the Greek letter sigma ($\sigma$).
