Electric Charges and Fields

This topic describes the electric charges and focuses on their origin. It also explains the meaning of positive and negative charges. Moreover, it gives some basic properties of electric charges and briefs us on charged materials.

This topic discusses the Coulomb’s law with formula and definition. It explains the permittivity of free space with SI units. We will learn how Coulomb’s law agrees with Newton’s third law with derivation.

In this topic, we will learn about the electric field, its formula, notation and significance. It discusses the effect of negative and positive charges in the electric field and about the test charge.

From this topic, we will get information about electric lines of forces. We will also discuss the meaning of different electric lines of forces. Besides, we will discuss their properties through some diagrams.

This topic explores the meaning and importance of electric flux. It also highlights the gauss's law related to electric flux. We will also explore some applications of gauss law and learn how to find the electric field due to infinite wire.

In this topic, we will read about the electric field of a dipole. We will learn how to calculate it and discuss its physical significance. Furthermore, it describes the magnitude and direction of the electric dipole moment.

From this topic, we will try to understand the concept of force and torque. We will learn how to find the torque on an electric dipole in a uniform electric field. It also gives the formula to calculate force.
