Assuming a stable, static status, we use Gauss's law:
Let's assume we're discussion a sphere, even though it works for every shape, it's just to simplify things.
If I wrap the inside of the sphere, I will get 0 electric field flow through my "wrapper", because if I had an electric field, it wouldn't have been a static, stable status.
So I keep making bigger and bigger wrappers, almost touching the edges of the sphere, but still no electrical field, which implies no electric charge in the wrapper (aka, inside the conductor). When I place the wrapper outside of the conductor, I find that there is an electrical field. which implies it can only be on the outer surface.
The surface charge density will remain constant at 30 nC/cm^2 even if the radius of the disk is doubled. Surface charge density is independent of the size of the object and depends only on the distribution of charge over its surface area.
no gauss low is only applicable for closed paths. a plane sheet is not a closed path. for applying gauss law the charge must be inside the closed loop or path... ========================== I'll say "yes". Gauss' law says that the electric flux through a closed surface is proportional to the amount of charge inside the closed surface. The shape of the surface doesn't matter, and the shape of the charge distribution inside it doesn't matter either. If a closed surface encloses a part of a sheet of charge, then the flux through the surface is proportional to the amount of charge that's on the part of the sheet inside the surface. That doesn't bother me at all.
Static charge builds up on the surfaces of materials because the electrons move more easily in materials compared to the protons. When two materials come into contact, electrons can transfer from one material to the other, leading to an imbalance of charges on the surface of the materials. This imbalance creates a static charge on the surface.
The conservation of charge law from Maxwell's equations states that the total electric charge within a closed system remains constant over time. This means that electric charge cannot be created or destroyed, only transferred from one object to another. Mathematically, this is represented by the divergence of the electric current density being equal to the negative rate of change of the charge density.
Insulators do not conduct electricity well, so when they come into contact with another material and rub against it, electrons are transferred between the two materials more easily. This transfer of electrons leads to one material becoming positively charged and the other becoming negatively charged, resulting in static electricity buildup on insulators.
charges reside only on the surface of a solid conductor. here charges maeans the charges which are free to move inside the conductor. we know very well that any particle or body always tries to acquire minimum potential energy. because the charges will acquire min. P.E only when they are on the surface.
The surface charge density will remain constant at 30 nC/cm^2 even if the radius of the disk is doubled. Surface charge density is independent of the size of the object and depends only on the distribution of charge over its surface area.
The charge all resides on the surface of the sphere, whether or not there's anything inside the surface. In principle, there's no limit on the amount of charge that can be jammed onto the sphere. The only limit is a practical one, that is, how much charge you can move and transfer to the sphere before it starts arcing back to the machinery or the support that's holding it.
Molecular compounds are poor conductors because they have no charge. Molecular compounds are simply just covalent bonds. Since covalent compounds dont give or take, they SHARE valence electrons they have no charge. Electricity is only created by positive and negative electrons, but since a molecular compound has no charge they are poor conductors. ONLY MOST ARE POOR CONDUCTORS. Why? Sometimes there is an unbalance and some molecules like Water tend be favor positive or negative, water for instance is just slightly negative.
Each telephone line uses only two conductors.
No, they do not.

Sweetness was previously believed to reside only at the tip, however newer research shows that taste occurs for all five sensations over the entire surface of the tongue.
The cylinder is given a static charge which attracts the toner particles - they only stick to the areas with static charge.

There are only two hemispheres, the northern and the southern.
Static charge builds up on the surfaces of materials because the electrons move more easily in materials compared to the protons. When two materials come into contact, electrons can transfer from one material to the other, leading to an imbalance of charges on the surface of the materials. This imbalance creates a static charge on the surface.
