ELECTRIC FIELD INTENSITY

ELECTRIC FIELD INTENSITY

It is defined at any point as the force experienced by unit positive charge placed at that point.

The electric field intensity at any point is the strength of electric field at that point.

If F  is the force acting on a test charge + q0 at any point, then electric field intensity at this point is given by

E = F/q0

Electric field intensity is a vector. The direction of E is the same as the direction of F that is E is along the direction in which the test charge  + q0 would tend to move.

The S.I. unit of electric field intensity is newton per coulomb.
