(N/A) Electric field intensity at a point is defined as the electrostatic force experienced by a unit positive test charge placed at that point.
Mathematically,it is expressed as $\vec{E} = \frac{\vec{F}}{q_0}$,where $\vec{F}$ is the force on a test charge $q_0$.
The $SI$ unit of electric field intensity is $\text{Newton per Coulomb}$ $(N/C)$ or $\text{Volt per meter}$ $(V/m)$.
