Electric field inside a charged surface

Click For Summary
SUMMARY

The electric field inside a conductor is definitively zero, as all charges accumulate on the surface, allowing them to distribute themselves to minimize repulsion, as described by Gauss' Law. In contrast, the electric field within an insulator is not necessarily zero; it varies based on the charge density and distribution throughout the material. This distinction is crucial for understanding electrostatics and the behavior of different materials under electric fields.

So just to verify (i'm not sure about this):

The electric field inside a conductor is zero?

the electric field inside an insulator is not necessarily zero?

am i right so far?

Yeah, the reason is because a conductor allows all the charge to accumulate on the surface and distribute itself in a way so that the charges are able to "move as far away from each other as possible"...this causes the electric field inside to cancel via Gauss' Law. In the insulator, charge can be spread throughout the body so the electric field is dependent on the charge density and its distribution inside the object.
