does flux depends on electric field or just the enclosed charges only

The flux of electric field coming out of a closed volume through its external surface is proportional to the charge inside.

The charge is the cause. The electric field is the result.

Flux is defined by the electric field passing through an area. For an enclosed area, it is proportional to the charge inside.

The flux depends on both the electric field and the enclosed charges. To understand this, let's discuss the concept of electric flux.

Electric flux is a measure of how much electric field passes through a certain area. Mathematically, it is defined as the dot product of the electric field vector and the surface area vector. Flux is typically denoted by the symbol Φ (phi).

Φ = E ⋅ A

Where:
- Φ represents electric flux
- E represents the electric field
- A represents the area through which the electric field is passing

Now, let's consider two scenarios:
1. Changing electric field with fixed enclosed charges:
In this case, if the electric field passing through a certain area changes, the electric flux will also change. This means that electric flux is influenced by the electric field.

2. Fixed electric field with changing enclosed charges:
Similarly, if the amount of enclosed charges within a given area changes, the electric flux will also change. Therefore, electric flux is influenced by the enclosed charges.

Hence, it is important to take into account both the electric field and enclosed charges when discussing electric flux.
