# Electric Field Intensity

on . Posted in Electrical Engineering

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.

## Electric field Intensity formula

$$\large{ E_i = \frac{ F }{ Q } }$$
Symbol English Metric
$$\large{ E_i }$$ = electric field intensity - $$\large{\frac{V}{m}}$$
$$\large{ Q }$$ = electric charge $$\large{ C }$$  $$\large{A-s}$$
$$\large{ F_e }$$ = electrostatic force $$\large{ lbf }$$  $$\large{N}$$ Tags: Electrical
