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 \(\large{ lbf }\)  \(\large{N}\)
