1. ELECTRIC CHARGES AND FIELDS
This chapter delves into the concept of electric charges and fields, introducing the fundamental nature of electric charges, their interactions, and the properties of both conductors and insulators. It explains Coulomb's Law, the concept of electric fields, and the principles governing electric dipoles and flux, alongside Gaussian surfaces. The chapter concludes with significant applications of these concepts in understanding electric behavior in various configurations.

What we have learnt
- Electric charges come in two types: positive and negative, where like charges repel and unlike charges attract.
- Coulomb's law provides a quantitative understanding of the forces between point charges and outlines the fundamental principles of electric interactions.
- Electric fields represent the influence of charges in space, and the concept is crucial for understanding interactions without requiring direct contact.
Key Concepts
- -- Electric Charge
- A property of matter that causes it to experience a force when placed in an electromagnetic field.
- -- Coulomb's Law
- A law stating that the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
- -- Electric Field
- A field around a charged object where other charges experience a force.
- -- Dipole Moment
- The measure of the separation of positive and negative charges in a system, represented as a vector.
