Everything in
this world is made up of tiny particles called "atoms", and each atom
is the made up of “protons", "neutrons", and
"electrons."
Insulators
Annotations:
These materials are made up of atoms which hold their electrons with a stronger force. Electrons could not flow freely from one atom to another - high resistivity.
Conductors
Annotations:
These materials are made up of atoms which hold their electrons with a loose force. Electrons could flow freely from one atom to another - low resistivity.
