Why is it that when you have an insulator, the charges are uniformly distributed but in a conductor, the charges are only at the surface?
A uniform charge distribution means that there are no concentrated areas of excess or deficiency of charge on the surface of the conductor. This is important because it ensures that the electric field within the conductor is also uniform, allowing for the flow of current without any interference or resistance.
A uniform charge distribution is essential for a conductor to have high conductivity. When there is an uneven distribution of charges, it creates regions of high and low electric potential, causing electrons to move towards areas of lower potential and creating resistance. With a uniform charge distribution, the electric potential remains constant, and the flow of electrons is not hindered, resulting in high conductivity.
Conductors have the ability to easily transfer electric charge due to the presence of free electrons. These free electrons can easily move and distribute themselves evenly on the surface of the conductor. In contrast, insulators do not have free electrons, and therefore, charge distribution is not possible. They have a fixed arrangement of atoms and cannot conduct electricity.
Insulators do not have free electrons, so the charges on their surface are not able to move and distribute themselves evenly. The atoms in insulators have tightly bound electrons, and any excess charge on the surface will remain in one location, creating an uneven charge distribution.
In conductors, a uniform surface charge distribution allows for the electric field to be evenly distributed, allowing for easy flow of current. In insulators, the non-uniform surface charge distribution results in an uneven electric field, which hinders the flow of current. This is why conductors are used to transfer electricity, while insulators are used to prevent the flow of electricity.
