Electric Field Lines: Electric field lines are imaginary lines used to visualize and represent the direction and strength of an electric field around a charged object.

Conductors vs Insulators: Conductors are materials that allow electrons to move freely, while insulators are materials that do not allow easy movement of electrons.

Conservation of Charge:

The principle stating that within an isolated system, the total electric charge remains constant. Charge cannot be created or destroyed, only transferred from one object to another.
