Electric flux
Electric flux is a concept in physics that describes the electric field passing through a given area or surface. It is a measure of the flow of electric field lines through that area. Electric flux is defined as the dot product of the electric field vector (E) and the area vector (A) of a surface:
Electric Flux (Φ) = E · A
Here, the dot product takes into account the angle between the electric field and the area vector. Electric flux is a scalar quantity and is measured in units of electric field times area (N·m²/C).
Electric flux is closely related to Gauss’s Law, which states that the electric flux through a closed surface is directly proportional to the total charge enclosed by that surface divided by the permittivity of the medium. Gauss’s Law is a powerful tool for calculating electric fields and understanding the behavior of electric charges.
Understanding electric flux is essential in various areas of physics, such as electrostatics, electromagnetism, and electric circuits. It helps in analyzing electric fields and their interactions with charges and conducting surfaces.
The Physics syllabus for AIIMS includes the topic of Electric Flux. Electric flux is a measure of the electric field passing through a given area. It is defined as the dot product of the electric field and the area vector. The formula to calculate electric flux is:
Electric Flux (Φ) = E · A
Here, E represents the electric field vector, and A represents the area vector. The dot product is used to account for the angle between the electric field and the area vector. Electric flux is a scalar quantity and its unit is Newton meters squared per coulomb (N·m²/C).
In addition to understanding the concept of electric flux, you may also be required to solve problems involving Gauss’s Law, which relates electric flux to the charge enclosed by a closed surface. Gauss’s Law states that the electric flux through a closed surface is directly proportional to the charge enclosed by that surface divided by the permittivity of the medium.
It is important to have a solid understanding of vectors, vector algebra, and the principles of electromagnetism to effectively grasp the concept of electric flux and its applications in various scenarios.

Case Study on Physics syllabus Electric flux
Case Study: Electric Flux in a Charged Sphere
In this case study, we will explore the concept of electric flux by considering a charged sphere. Let’s imagine a conducting sphere with a uniform charge distribution, carrying a total charge Q. We want to calculate the electric flux through a closed surface surrounding the sphere.
- Problem Statement: Consider a conducting sphere of radius R and total charge Q. Determine the electric flux through a closed surface S, which encloses the sphere.
- Solution: To solve this problem, we can apply Gauss’s Law, which states that the electric flux through a closed surface is directly proportional to the total charge enclosed by that surface divided by the permittivity of the medium.
a. Gaussian Surface Selection: For a conducting sphere, it is convenient to choose a spherical Gaussian surface with the same center as the charged sphere. Let’s consider a spherical surface S with radius r > R (the radius of the conducting sphere).
b. Electric Field Calculation: Inside the conducting sphere, the electric field is zero due to charge redistribution. Outside the sphere, the electric field is similar to that of a point charge located at the center of the sphere. Thus, for r > R, the electric field magnitude is given by E = kQ/r², where k is the Coulomb’s constant.
c. Flux Calculation: To calculate the electric flux through the Gaussian surface S, we need to determine the electric field and the area vector. The area vector is directed radially outward, and its magnitude is equal to the surface area of the sphere, A = 4πr².
The electric flux (Φ) through the surface S is given by the dot product of the electric field and the area vector:
Φ = E · A = E * A * cos(θ),
where θ is the angle between the electric field and the area vector. Since the electric field and area vector are parallel, θ = 0°, and cos(θ) = 1.
Substituting the values, we have:
Φ = (kQ/r²) * (4πr²) = 4πkQ.
Therefore, the electric flux through the closed surface S surrounding the charged sphere is 4πkQ, where k is the Coulomb’s constant.
- Conclusion: In this case study, we considered a conducting sphere with a uniform charge distribution and calculated the electric flux through a closed surface surrounding the sphere using Gauss’s Law. The electric flux was found to be 4πkQ, where k is the Coulomb’s constant and Q is the total charge enclosed by the surface. This case study demonstrates the application of electric flux in understanding the behavior of charges and electric fields in specific geometries.
