$E \cdot \mathrm{dS} = {\phi}_{f l u x}$

#### Explanation:

To be very straight :
Electric flux is defined as the total number of field lines of force passing through an area.
$E \cdot \mathrm{dS} = {\phi}_{f l u x}$

here $E$ stands for magnitude of electric field
and $\mathrm{dS}$ stands for the area.
