What is the relation between electric intensity and electric flux ?

Explanation

To establish the relation between electric intensity (electric field intensity) and electric flux, we can follow these steps:

### Step 1: Understand Electric Field Intensity
Electric field intensity (E) at a point in space is defined as the force (F) experienced by a unit positive charge (q) placed at that point. Mathematically, it is expressed as:
\[ E = \frac{F}{q} \]

### Step 2: Define Electric Flux
Electric flux (Φ) through a surface is defined as the product of the electric field intensity (E) and the area (A) of the surface through which the field lines pass, taking into account the angle (θ) between the electric field lines and the normal to the surface. The formula for electric flux is:
