Electric Field:
The electric field due to a charge is the space around that charge where it experiences a force.
The presence of an electricfield around a charge cannot be detected unless another charge is brought towards it.
If a test charge g is placed near a charge q which being the source of electric field, an electrostatic force F will act on the test charge.
Electric Field Intensity :
Electric field at a point is measured in terms of electric field intensity.
Electric field intensity at a point in an electric field is defined as the force experienced by a unit positive charge kept at that point.
Electric lines of force :
Electric line of force is an imaginary straight or curved path along which a unit positive charge tends to move in an electric field.
