Electric flux is defined as the product of the electric field and the area, expressed as Φ = EA, because it quantifies the number of electric field lines passing perpendicularly through a surface. The equation reflects that electric flux is influenced by the strength of the electric field (E) and the size of the area (A) through which it passes. It is important to note that electric flux is not directly proportional to charge; rather, it can remain constant with varying distances from the charge. The formula also incorporates the angle between the electric field and the surface area, represented as cos(x). Understanding electric flux is crucial for analyzing electric fields and their interactions with surfaces.
