Electric Field Intensity - Definition, Formula and Unit

Electric Field Intensity - Definition, Formula and Unit

In this post, we will cover the Electric Field Intensity Definition, Formula and Unit that will help you to understand Electric Field Intensity better.

Electric Field Intensity Definition-

Electric Field Intensity (E) may be defined in the following ways-

1. Electric field intensity is the force experienced by a unit positive charge placed at that point.

E = F/Q newton/coulomb (i.e., force per unit charge).

2. Electric field intensity is equal to the lines of force passing normally through a unit cross-section at that point.

E=Q/εA

3. Electric intensity at any point in an electric field is equal to the potential gradient at that point.

E = dV/dX volt/meter.

Electric Field Intensity Formula-

Electric field intensity Formula is given by-

E = F/Q newton/coulomb

or

E=Q/εA

or

E = dV/dX volt/metre

Electric Field Intensity Unit-

The Unit of Electric field intensity is newton/coulomb or volt/meter.
