An electrolite
An infinite number of lines can pass through any given point.
A conductor.
Those are called insulators.
A materiel that allows an electric charge to pass through it is an conducter (copper, for example)
Infinitely many.
Just one.
It is named "Insulator".
current electricity is the flow of charge is called the current and it is the rate at which electric charges pass through a conducter
Superconductors
