No, the electric field is not dependent on the area of the cross-section. The electric field at a point is determined by the charge distribution and the distance from the charges.
The electric field (\(E\)) at a point in space is given by Coulomb's law (for point charges) or by Gauss's law (for more complex charge distributions). Both of these laws describe how the electric field is generated by charges and how it behaves in space.
For a point charge, the electric field depends on the charge (\(q\)) and the distance (\(r\)) from the charge, but not on the area of the cross-section through which you measure the field.
However, if you're dealing with a uniform electric field, like between the plates of a parallel plate capacitor, the electric field is the same everywhere between the plates, and it is not influenced by the area of the plates or the cross-sectional area through which you measure it.
In summary, the electric field itself doesn't change with the area of the cross-section. But the flux of the electric field (which is related to the area) can depend on the area because the flux is calculated as the product of the electric field and the area through which the field lines pass.
