How many free electrons are in a copper atom? – Wisdom-Advices
Web23 okt. 2024 · Where I is current flow, n is the free electron density, e is the charge of an electron and A is the cross sectional area. First we cross-sectional area of the wire: Area; We substitute in our given values. So, Cross-sectional area of the wire is . Now we substitute all our values into equation for Drift velocity. Therefore, the drift velocity ... WebIn this post, I will explain why metals are such good electrical conductors, and also explain how nonmetals like water and glass can also become conductors. Metals conduct electricity because they have “free electrons.”. Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom.
