Electric flux
Electric flux is a fundamental concept in electromagnetism that measures the electric field passing through a given surface. It quantifies the amount of electric field lines that penetrate a surface, providing insights into the distribution of electric charge.
Electric flux (ΦE) is defined as the dot product of the electric field (E) and the area vector (A) of a surface:
ΦE=E⋅A
where:
- ΦE is the electric flux
- E is the electric field
- A is the area vector of the surface
The electric field is a vector that describes the force experienced by a unit positive charge placed at a particular point. The area vector points perpendicular to the surface and has a magnitude equal to the area of the surface.
The unit of electric flux is N·m²/C or V·m, and it is a scalar quantity.
To calculate the electric flux through a closed surface, you can use the following steps:
- Determine the direction and magnitude of the electric field at each point on the surface.
- Determine the area vector for each small area element on the surface.
- Take the dot product of the electric field and the area vector at each point.
- Sum up the contributions from each small area element to find the total electric flux.
Gauss’s law is a fundamental principle related to electric flux. It states that the total electric flux passing through a closed surface is proportional to the total electric charge enclosed by that surface. Mathematically, it can be expressed as:
ΦE=ϵ0Qenc
where:
- ΦE is the electric flux
- Qenc is the total electric charge enclosed by the surface
- ϵ0 is the permittivity of free space (a constant)
Gauss’s law provides a powerful tool for calculating electric fields and charges in symmetric systems by utilizing the concept of electric flux.
Understanding electric flux is crucial in various areas of electromagnetism, including electrostatics, electric field analysis, and electromagnetic induction. It has applications in physics, engineering, and many other fields where electric phenomena are involved.
The syllabus for the Physics section of the AIIMS entrance examination may vary slightly from year to year, so it’s always a good idea to refer to the official AIIMS website or the information bulletin for the most up-to-date and accurate syllabus. However, I can provide you with a general overview of the topic of electric flux, which is a fundamental concept in electromagnetism.
Electric flux is a measure of the electric field passing through a given surface. It helps us understand how much electric field is penetrating a particular area. The electric flux through a closed surface is directly proportional to the total electric charge enclosed by that surface.
Mathematically, electric flux (ΦE) is defined as the dot product of the electric field (E) and the area vector (A) of a surface:
ΦE=E⋅A
where:
- ΦE is the electric flux
- E is the electric field
- A is the area vector
The unit of electric flux is N·m²/C or V·m, and it is a scalar quantity.
To calculate the electric flux through a closed surface, you need to consider the orientation of the electric field and the surface area vector. The dot product ensures that only the component of the electric field perpendicular to the surface contributes to the electric flux.

How is Required AIIMS-SYLLABUS Physics syllabus Electric flux
Electric flux is a measure of the electric field passing through a given surface. It quantifies the amount of electric field lines that penetrate a surface and provides information about the distribution of electric charge.
The calculation of electric flux involves considering the electric field and the area vector of a surface. Mathematically, electric flux (ΦE) is defined as the dot product of the electric field (E) and the area vector (A) of the surface:
ΦE=E⋅A
where:
- ΦE is the electric flux
- E is the electric field
- A is the area vector of the surface
The electric field is a vector quantity that describes the force experienced by a unit positive charge placed at a particular point. The area vector is a vector perpendicular to the surface with a magnitude equal to the area of the surface.
To calculate the electric flux through a closed surface, you need to determine the direction and magnitude of the electric field at each point on the surface. You also need to determine the area vector for each small area element on the surface. Taking the dot product of the electric field and the area vector at each point, and summing up the contributions from each small area element, will give you the total electric flux.
Gauss’s law is a fundamental principle related to electric flux. It states that the total electric flux passing through a closed surface is proportional to the total electric charge enclosed by that surface. Mathematically, it can be expressed as:
ΦE=ϵ0Qenc
where:
- ΦE is the electric flux
- Qenc is the total electric charge enclosed by the surface
- ϵ0 is the permittivity of free space
By applying Gauss’s law, you can determine the electric flux and use it to analyze and understand electric fields and charges in various systems and configurations.
Remember that this explanation provides a general understanding of electric flux, but for the specific details and applications relevant to the AIIMS Physics syllabus, you should consult the official AIIMS sources.
Case Study on AIIMS-SYLLABUS Physics syllabus Electric flux
Certainly! Let’s consider a case study on electric flux to illustrate its practical application.
Case Study: Electric Flux through a Charged Sphere
Scenario: Suppose we have a solid sphere of radius R carrying a total charge Q. We want to calculate the electric flux through a closed surface surrounding the sphere.
Solution: To solve this case, we will apply Gauss’s law, which relates the electric flux passing through a closed surface to the total charge enclosed by that surface.
- Surface Selection: Let’s choose a closed surface that is a sphere with radius r>R. This surface completely encloses the charged sphere.
- Calculation of Electric Flux: According to Gauss’s law, the electric flux (ΦE) passing through the closed surface is given by:
ΦE=ϵ0Qenc
where Qenc is the total electric charge enclosed by the surface and ϵ0 is the permittivity of free space.
In this case, the enclosed charge Qenc is simply equal to the total charge of the sphere Q. Therefore, the electric flux can be written as:
ΦE=ϵ0Q
- Calculation of Charge Q: The charge Q of the sphere can be calculated using the formula:
Q=34πR3⋅ρ
where ρ is the charge density (charge per unit volume) of the sphere.
- Substitution and Simplification: Substituting the expression for Q into the equation for electric flux, we have:
ΦE=ϵ034πR3⋅ρ
- Simplification and Result: Simplifying the expression further, we obtain the final result for the electric flux through the closed surface surrounding the charged sphere:
ΦE=34πR3⋅ϵ0ρ
This result quantifies the electric flux passing through the chosen closed surface surrounding the charged sphere in terms of the sphere’s radius R and the charge density ρ.
This case study demonstrates the practical application of electric flux in calculating the electric field through a closed surface using Gauss’s law. By understanding electric flux, we can analyze and predict the behavior of electric fields and charges in various systems and configurations, providing valuable insights in the field of electromagnetism.
