It is well known that no electric fields exist inside a hollow conductor, even if there are charges present outside. … A charge inside a hollow conductor produces a charge distribution on the outer surface of the conductor, and this induced charge distribution creates an electric field outside the closed conductor.
What is the electric field inside a hollow sphere?
According to Gaussian’s law the electric field inside a charged hollow sphere is Zero. This is because the charges resides on the surface of a charged sphere and not inside it and thus the charge enclosed by the guassian surface is Zero and hence the electric field is also Zero.
What is the electric field intensity inside a hollow conductor?
As we know that the electric field intensity inside the hollow spherical charged conductor is zero. Hence, the work done in moving a point charge inside the hollow spherical conductor is also zero. This implies that the potential difference between any two points inside or on the surface of the conductor is zero.
Why is there no electric field inside the hollow electrode?
It is well known that no electric fields exist inside a hollow conductor, even if there are charges present outside. … A charge inside a hollow conductor produces a charge distribution on the outer surface of the conductor, and this induced charge distribution creates an electric field outside the closed conductor.
Why is the potential inside a conductor constant?
As inside the conductor the electric field is zero, so no work is done against the electric field to bring a charge particle from one point to another. … Since E=0, therefore the potential V inside the surface is constant.
Why potential is constant inside a hollow sphere?
The potential difference between the shells depends on charge of inner shell. Reason: Potential due to charge of outer shell remains same at every point inside the sphere.
What is the direction of force in an electric field?
The electric field direction points straight away from a positive point charge, and straight at a negative point charge.
What is the electric field inside an insulator?
Inside a conductor the potential V is constant and the surfaces of a conductor are an equipotential. In an insulator charges cannot move around, and the charge density can have any form. If ρ(r) = 0, the potential is non-uniform, and E = 0 inside the insulator.
