What is electric flux directly proportional to?
2 Answers
Electric flux is directly proportional to the electric field strength and the area through which the field lines pass, as well as the cosine of the angle between the electric field and the normal to the surface. Mathematically, this relationship is expressed as:
\[
\Phi_E = E \cdot A \cdot \cos(\theta)
\]
where:
- \(\Phi_E\) is the electric flux,
- \(E\) is the electric field strength,
- \(A\) is the area through which the field lines pass,
- \(\theta\) is the angle between the electric field and the normal to the surface.
So, in summary, electric flux is directly proportional to the electric field strength and the area, with the orientation of the surface also playing a crucial role.

Electric flux is directly proportional to the following factors:
1. **Electric Field Strength (E):** Electric flux (Φ) is proportional to the magnitude of the electric field. If the electric field strength increases, the flux through a given surface also increases. Mathematically, it can be expressed as \( \Phi = E \cdot A \cdot \cos \theta \), where \( E \) is the electric field, \( A \) is the area through which the field lines pass, and \( \theta \) is the angle between the electric field and the normal to the surface.
2. **Surface Area (A):** Electric flux is proportional to the area of the surface through which the electric field lines pass. For a given electric field, a larger surface area will intercept more field lines, leading to a larger flux.
These relationships are encapsulated in the formula:
\[ \Phi = E \cdot A \cdot \cos \theta \]
where:
- \( \Phi \) is the electric flux,
- \( E \) is the electric field strength,
- \( A \) is the area of the surface through which the field lines pass,
- \( \theta \) is the angle between the electric field direction and the normal (perpendicular) to the surface.
In summary, electric flux is directly proportional to both the electric field strength and the area of the surface, and it depends on the angle between the field and the surface.
