The electric field is a physical field surrounding electric charges. It is proportional to the Coulomb force exerted on a charge in position :

For point charges

For a singe point charge in point and with charge :

Where is the electric field vector. It is generated by other point charges in space. It directly comes from Coulomb's law.

For continuous charge distributions

For continuous charge distribution functions, the generated electric field is the following:

Note that this form can be used for point charges as well if we substitute Dirac deltas to the point charges.
