Electric Field Intensity

Electric field intensity, abbreviated as \(E_i\), is a vector field that describes the force per unit positive charge experienced by a test charge at a given point in space due to the presence of other charges.  It is the space around an electrically charge body in which a charge experiences a force of attraction or repulsion.

For a system of multiple charges, the total electric field at a point is the vector sum of the individual electric fields produced by each charge.  It's important to note that the electric field is a concept in electromagnetism and plays a role in understanding the behavior of charged particles and the principles of electrical circuits.
