Those who are looking for an answer to the question «Why is there no electric field in a hollow conductor?» often ask the following questions:

👉 Does a hollow conductor have electric field?

electric field in hollow conductor. when we have a hollow conductor and we charge it then the quantity of charges and electric on and in inner surface of conductor material is zero and this is okay .But is the electric field also zero inside the air cavity and why? (suppose that there is no charge in the air cavity and that the conductor is ...

👉 Why is there no electric field inside a hollow conductor?

Active 11 months ago. Viewed 10k times. 1. If you have a conducting hollow sphere with a uniform charge on its surface, then will the electric field at every point inside the shell be 0. The reason the electric field is 0 at the center is clear from the symmetry of the sphere, but for a point at a certain distance from the center, shouldn't a net ...

There will be no electric field within the metal of the sphere itself. If there WERE an electric field within the conductor itself, charges would move around and cancel the field. There will be an electric field OUTSIDE the sphere that is caused by the enclosed bit of charge.

The electric field is zero within the conductor because the charges are all at rest in an electrostatic situation. But the electric field inside a cavity within the conductor is not necessarily zero because it isn't part of the conductor, as my book says. Then i encountered a topic about electrostatic shielding and it says that the electric field ...

What else the electric field inside the conductors is zero. If there was an electric field then the mobile charge carrier would feel a force on them and move so it would cease to be static electricity. It is the $+Q$ and $-Q$ induced charges on the surface of the inner conducting shell which ensure that the electric field inside the conductor is zero. The net charge on that inner shell is $+Q + (-Q) = 0$.

$\begingroup$ @alvoutila, if there is an electric field inside the hollow region, the electric potential at some points must be higher or lower than the potential of the inner surface. But, this would mean that there is a local minimum or maximum of the potential in the hollow region. But, this is mathematically impossible!

When, after less than a microsecond, the new static conditions are achieved: There can be no electric field inside the conductor or else the free-to-move-charges in it would still be moving around within the volume of the conductor. There can be no unbalanced charge within the volume of the conductor or else there would be an electric field inside the conductor.

To find field inside the hollow sphere we can take take Gaussian surfaces with radii ranging from R=0 to R=r. Any of these surfaces the charge enclosed is zero and hence field at all the points on these surfaces is zero. Thus, electric field in side a hollow sphere of conductor is zero.

Is there is an electric field inside a solid conductor?

Not to quote myself but.... Firefox123 said: There are many electric fields inside a conductor...the reason there is no "net" electric field is because the charges balance themselves in such a way to cancel the overall electric field. As far as "electrostatic equilibrium" is concerned.....

How electric field inside a conductor?

An electrical conductor is a solid that contains many free electrons. Free electrons can move freely around, but cannot leave the surface. When we charge a conductor, the electrons will move around until they have arranged themselves to produce a zero electric field everywhere inside the conductor.

Is electric field 0 inside conductor?

The charges reside only on the surface of the conductor, it is absent inside the conductor. So by applying Guass law we can say that there is no electric field in the conductor. Gauss law states that the total electric flux through a hypothetical closed surface is always equal to (1/ε 0) times the net charge enclosed by the surface. The ...

What is electric field in a hollow sphere?

The electric field inside a hollow metallic sphere is zero. so the work done is also zero. suppose Va is thepotential on the inside and Vb is the potential on the surface, then Vb - Va = 0 or Vb = Va. Hence thepotential is the same inside as on the surface.

Is there an electric field on the surface of a conductor?

The electric field is zero inside a conductor. Just outside a conductor, the electric field lines are perpendicular to its surface, ending or beginning on charges on the surface. Any excess charge resides entirely on the surface or surfaces of a conductor.

What is electric field inside a conductor?

The electric field inside the conductor (E1) is zero. In other words, if a cavity is completely enclosed by a conductor, no distribution of charges outside can ever produce any field inside. But no field is no force, so that’s how the shielding really works!

How does a conductor change an electric field?

Free charges move within the conductor, polarizing it, until the electric field lines are perpendicular to the surface. The field lines end on excess negative charge on one section of the surface and begin again on excess positive charge on the opposite side. No electric field exists inside the conductor, since free charges in the conductor would continue moving in response to any field until it was neutralized.
