Understanding Electric Flux: A Comprehensive Guide to Calculating and Applying It

Welcome to our manual on electric-powered flux and a way to calculate it with the usage of an electric-powered flux calculator. Whether you’re a scholar delving into the arena of electromagnetism or an expert in want of specific calculations in your projects, understanding electric flux is important. In this article, we’ll ruin the idea of electrical flux, discover its importance in several applications, and offer a step-with the aid of-step manual on the use of an electric-powered flux calculator correctly.

What is Electric Flux?

Electric flux is a fundamental idea in electromagnetism that measures the float of an electric area through a given floor. It represents the quantity of electrical field traces passing through a floor, indicating the power of the electrical discipline in that area. Mathematically, electric-powered flux (Φ𝐸) is defined as the dot fabricated from the electric area (𝐸) and the region vector (𝐴) of the surface, incorporated over the surface vicinity (𝐴).

Gauss's Law

Gauss's Law relates the total electric flux (\( \Phi_E \)) passing through a closed surface to the total charge (\( Q_{\text{enc}} \)) enclosed by that surface. Mathematically, it can be expressed as:

\[ \Phi_E = \frac{Q_{\text{enc}}}{\varepsilon_0} \]


  • \( \Phi_E \) is the electric flux.
  • \( Q_{\text{enc}} \) is the total charge enclosed by the closed surface.
  • \( \varepsilon_0 \) is the electric constant, also known as the permittivity of free space.

Gauss's Law is a fundamental principle in electromagnetism, providing a powerful tool for calculating electric fields in situations with high symmetry.

Electric Flux Calculator Formula

The formula for calculating electric flux (\( \Phi_E \)) is:

\[ \Phi_E = \oint_S \vec{E} \cdot d\vec{A} \]


  • \( \Phi_E \) is the electric flux.
  • \( \vec{E} \) is the electric field.
  • \( d\vec{A} \) is an infinitesimal area vector.
  • \( \oint_S \) represents the surface integral over the closed surface \( S \).

Electric Flux Calculation Examples

Example 1: Electric Flux through a Closed Surface

Consider a closed surface \( S \) with an electric field \( \vec{E} = 3\hat{i} + 4\hat{j} \) N/C passing through it. The surface has an area of 5 m². Calculate the electric flux (\( \Phi_E \)) through the surface.

\[ \Phi_E = \oint_S \vec{E} \cdot d\vec{A} \]

\[ \Phi_E = \int_S (\vec{E} \cdot \hat{n}) \, dA \] (For a closed surface)

\[ \Phi_E = \int_S (3dx + 4dy) \]

\[ \Phi_E = \int_0^5 \int_0^1 (3dx + 4dy) \]

\[ \Phi_E = \int_0^5 (3 + 4) \, dx \]

\[ \Phi_E = \int_0^5 7 \, dx \]

\[ \Phi_E = 7 \cdot (5 - 0) \]

\[ \Phi_E = 35 \, N \cdot m^2/C \]

Example 2: Electric Flux through an Open Surface

Consider an open surface \( S \) with an electric field \( \vec{E} = 2\hat{i} + 3\hat{j} \) N/C passing through it. The surface has an area of 8 m². Calculate the electric flux (\( \Phi_E \)) through the surface.

\[ \Phi_E = \int_S \vec{E} \cdot d\vec{A} \]

\[ \Phi_E = \int_S (\vec{E} \cdot \hat{n}) \, dA \] (For an open surface)

\[ \Phi_E = \int_S (2dx + 3dy) \]

\[ \Phi_E = \int_0^8 (2dx + 3dy) \]

\[ \Phi_E = \int_0^8 2 \, dx \]

\[ \Phi_E = 2 \cdot (8 - 0) \]

\[ \Phi_E = 16 \, N \cdot m^2/C \]
