How electricity is conducted in a metal?
Metals conduct electricity by allowing free electrons to move between the atoms. … Since like charges repel each other, the movement of one free electron within the lattice dislodges those in the next atom, and the process repeats – moving in the direction of the current, toward the positively charged end.
How do we get electricity from air?
