Your question: Where do electric field lines originate and terminate?

Electric field lines either originate on positive charges or come in from infinity, and either terminate on negative charges or extend out to infinity.

Where do electric fields originate?

Electric fields originate from electric charges, or from time-varying magnetic fields. Electric fields and magnetic fields are both manifestations of the electromagnetic force, one of the four fundamental forces (or interactions) of nature.

Can electric field lines begin or terminate?

Electrical field lines can only begin and terminate at charges.

Where do electric field lines end?

Electric field lines always extend from a positively charged object to a negatively charged object, from a positively charged object to infinity, or from infinity to a negatively charged object.

What is electric field direction?

The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point.

Where is the electric field strongest?

The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest.

Where do field lines must start?

Field lines must begin on positive charges and terminate on negative charges, or at infinity in the hypothetical case of isolated charges. The number of field lines leaving a positive charge or entering a negative charge is proportional to the magnitude of the charge.

Why do field lines start and end on conductor?

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. This of course presumes that our conductor does not surround a region of space where there was another charge.

Are electric field lines straight?

Electric field lines never intersect. 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 do electric field lines begin from positive and end at negative?

A field line is defined as a line that is always tangent to the field, and is oriented by the field. Since the electrostatic field is always directed away from positive charges and toward negative charges, field lines must go away from positive charges and toward negative ones.

What is the direction of the electric field at the corner?

The direction of the electric field is radially outward for a positive charge, and radially inward for a negative charge.
