## Can electric field lines go to infinity?

**The electrostatic field does go to infinity**, it is a long range force, but the strength diminishes with distance so in the limit as r –> infinity F –> 0. Charges an infinite distance away from each other would not affect each other.

## Do electric field lines ever end?

Electric field lines. Electric field lines provide a means to visualize the electric field. 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.

## Is electric field 0 at infinity?

Both the electric field vectors will point in the direction of the negative charge. … **The potential at infinity is zero**, and the potential at the midpoint of the dipole, due to the charges on the dipole, is also zero.

## How far do electric fields reach?

The range of the Coulomb force **is infinite** (the force between two charges Q1,Q2 separated by a distance r is given as F=Q1Q24πϵ0r2), with the implication that the photon has zero (rest) mass.

## Where do electric fields begin and end?

Field lines **start on positive charges and end on negative charges**. Rules for drawing field lines: Electric field lines begin on positive charges and end on negative charges, or at infinity. Lines are drawn symmetrically leaving or entering a charge.

## Are electric field lines continuous?

Yes, the electrostatic field line is **a continuous curve** because a unit charge always experiences a continuous force when it is placed in an electrostatic field. The unit charge is the charge that passes through the cross-section of an electric conductor that carries one ampere of current in one second.

## Why do field lines start and end on conductors?

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.
