			== Continuous charge ==

			A charged conductor can be approximated as an infinite number of point charges $dQ$, each creating an electric field at arbitrary point in space $A$:

			$$
			\vec E_{dQ \to A} = \frac{1}{4\pi\epsilon0}\frac{Q}{\left\\| \overrightarrow{PA} \right\\|}\widehat{PA}
			$$

			Therefore, the overall electric field at point $A$ is:

			$$
			\int \vec E_{dQ} dQ
			$$
