Do electric field lines ever end?

Since the electric field is a vector, electric field lines have arrows showing the direction of the electric field. Lines begin and end only at charges (beginning at + charges, ending at – charges) or at Infinity. Lines are closer together where the field is stronger.

Why electric field lines do not terminate in space?

The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential. If the electric field in a given region of space is zero, electric field lines do not exist.

Why is electric field outward?

The direction of the force that is exerted on a negative charge is opposite that which is exerted on a positive charge. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.

Why do field lines start and end on conductors?

If the electrons within a conductor have assumed an equilibrium state, then the net force upon those electrons is zero. The electric field lines either begin or end upon a charge and in the case of a conductor, the charge exists solely upon its outer surface. The lines extend from this surface outward, not inward.

Can field lines end without a charge?

Electrical field lines can only begin and terminate at charges.

Can electric field lines begin or terminate?

Field lines must begin on positive charges and terminate on negative charges, or at infinity in the hypothetical case of isolated charges.

Why are electric field lines always straight?

In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.

Why are electric lines of force not closed?

If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. Therefore, we say electrostatic field lines never form closed loops.

Why the electric field lines for positive charges is outward?

We know that charges with the same sign repel each other, So the force on the test charge would be outward (along the line joining them). So the electric field due to positive charge would radially outward.

Can electric field lines begin and end on the same conductor?

But the external surface of a charged conductor is always on equipotential surface. So it is not possible for a conductor being charged positively in on part and negetively in another part. Thus a field line cannot start from a conductor and end on the same.

Can electric field penetrate?

The plasma sheaths tend to shield the potential (or electric field) from penetrating into the plasma. Those results suggest that the externally applied electric field cannot penetrate into the plasma.
