Point Charge
Definition
A point charge is an idealized model used in physics to represent a particle with all its charge concentrated at a single point. It has no physical size but possesses an electrical charge.
Analogy
Think of a point charge as a tiny speck that carries an electrical charge. Just like how you can imagine dividing any object into smaller and smaller pieces until you reach its smallest component, we consider this smallest component as a point charge in physics.

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.
