It is probably worth starting to look at what an electric field is by defining what it is and then explaining how it all occurs and the effects of it.
Electric field definition:
An electric field results from each point in space where charge is present in any form. The magnitude and direction of the electric field are expressed by the value of E, called electric field strength which is often referred to as the electric field, or sometimes the electric field intensity.
The electric fields, charges and forces are explained by Coulomb’s Law. As the name indicated, Coulomb’s Law was developed by Charles-Augustin de Coulomb, a French Physicist. In 1785 he published three papers about electricity and magnetism and thin them he stated his law.
The development of Coulomb’s Law was a major milestone in the development of the theory of electromagnetism, and one that was sued as the foundations for many more discoveries in later years.
