The number of electric field lines that pass a specific location is referred to as electric flux. It is assumed that electric field lines begin with positive charges and conclude with negative charges. Electric field lines pointing toward a closed surface are considered negative, whereas those pointing away from a closed surface are considered positive.
Some of the major words used in the notion of electric flux must be understood in order to grasp the concept of electric flux. The following are the terms-
Electric flux may be defined as the measure of the dispersion of the electric field or the pace at which the electric field flows across a specific region. This phrase is used to define the strength of an electric field at any distance from the charge creating the field. The concept of flux is commonly associated with the lines of force that travel through a certain place. Lines of force passing across a certain area's surface are thus determined by three factors-
In electromagnetism, electric flux is the measurement of the electric field lines traversing the surface. Although an electric field cannot flow by itself, it is a method of describing the intensity of the electric field at any distance from the charge that creates the field.
Volt-meters are the SI unit of electric flux (V.m). Volt-metres (Vm), commonly known as newton meters squared per coulomb, is the SI unit of electric flux (N m² Cˉ¹). The standard units for measuring electric flux are kg.m³.sˉ³. Aˉ¹.
The dimensional formula for electric flux is M¹ L³ Tˉ³ Iˉ¹
Where,
M = Mass
I = Present
L stands for length.
T = Time
Electric Flux (𝞥🇪) = E x A x cos 𝞡 ... (1)
Where,
Magnitude of the Electric Field = E
Surface Area = A
The dimensional formula of area (A) = M⁰ L² T⁰ …(2)
Because the electric field = Force x Chargeˉ¹,
So, the Electric Field Formula = (M¹ L¹ Tˉ²) x (I¹ T¹)ˉ¹
Electric Field Dimensional Formula = M¹ L¹ Tˉ³ Iˉ¹ ... (3)
In equation, substitute equations (2) and (3) in the (1) equation,
Electric Flux (𝞥🇪) = E x A x cos 𝞡 or 𝞥🇪= [(M¹ L¹ Tˉ²) x (I¹ T¹)ˉ¹] x M⁰ L² T⁰ = M¹ L¹ Tˉ³ Iˉ¹
Thus, the electric flux dimensional formula is M¹ L¹ Tˉ³ Iˉ¹
The following are the steps for calculating electric flux-
Electric fields, also known as flux lines, are lines of force that exist around a charge and include the following characteristics:
The following things should be kept in mind-

Ans. Electric flux density is defined as the amount of electric flux traveling through a unit area perpendicular to the flux’s direction. The intensity of an electric field created by a free electric charge is measured by electric flux density.
Ans. The attribute of an electric field is electric flux. It is comparable to the number of forces that span a specific region. It is usually assumed that electric field lines begin with positive charges and end with negative charges. Negative field lines are directed into a closed surface, whereas positive field lines are directed away from a closed surface.
Ans. When the flux lines are pointed outwards, they are directed outwards.
Ans. Yes, it is a scalar quantity.
