Electric flux, abbreviated as \( \phi_e \), describes the quantity of electric field passing through a given surface. It represents the total number of electric field lines passing through a surface and provides a measure of the strength of the electric field through that surface.
Electric flux is a useful concept for analyzing electric fields and their interactions with charged objects and surfaces. It helps in understanding the distribution of electric field lines, determining the strength of the electric field, and applying principles such as Gauss's law to solve various electrostatic problems.
