Electric flux (Φ) is the measure of the number of electric field lines passing through a given surface.
It is a scalar quantity and its unit is Nm²/C.
Electric flux is proportional to the number of electric field lines and the area of the surface.
Mathematically, electric flux is represented as: Φ = E × A, where E is the electric field and A is the area of the surface.

Electric dipole moment (p) is a measure of the separation of positive and negative charges in a system.
It is a vector quantity and its unit is Cm.
Electric dipole moment is calculated as: p = q × d, where q is the charge and d is the distance between the charges.
Electric dipole moment is used to describe the behavior of molecules and atoms in electric fields.

Electric potential (V) is the potential energy per unit charge at a given point in an electric field.
It is a scalar quantity and its unit is V (volts).
Electric potential is related to the electric field by: E = -ΔV/Δx, where E is the electric field and ΔV is the change in potential.
Electric potential is used to calculate the electric potential energy of a charge in an electric field.

Electric field lines are imaginary lines that emerge from positive charges and enter into negative charges.
They are used to visualize the electric field around a charge or a system of charges.
The direction of electric field lines is tangent to the electric field at any point.
Electric field lines never intersect, and they are continuous curves.

A Gaussian surface is a closed surface in three-dimensional space used to calculate the electric flux.
The Gaussian surface is imaginary and can be of any shape, but it is usually chosen to be a sphere or a cube.
The electric flux through a Gaussian surface is proportional to the charge enclosed within the surface.
Gauss's law states that the total electric flux through a closed surface is proportional to the charge enclosed within the surface: Φ = Q/ε₀, where Φ is the electric flux, Q is the charge, and ε₀ is the electric constant.

Electric flux is a scalar quantity that measures the number of electric field lines passing through a given surface.
It has a unit of Nm²/C.
Electric flux is directly proportional to the number of electric field lines and the area of the surface.
Mathematically, electric flux is represented as: Φ = E × A, where E is the electric field and A is the area of the surface.
