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.
What else can I help you with?
What will the surface charge density be if the radius of the disk is doubledA circular disk has surface charge density 30 nCcm2.?
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.
Can Gauss's law be applied to sheet of charge?
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.
Why does static charge only build up on the surfaces of materials?
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.
What is the conservation of charge law from maxwell's equations?
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.
Why do insulators get easily charged by friction?
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.
Where does charge resides in case of conductors on surface or everywhere volume also?
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.
What will the surface charge density be if the radius of the disk is doubledA circular disk has surface charge density 30 nCcm2.?
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.
Will asolid metal sphere hold a larger electric charge than a hollow sphere of the same diameter where does the charge reside in esch case?
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.
Why are most molecular compound poor conductors?
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.
How many conductors does a POTS line use?
Each telephone line uses only two conductors.
Do gold silver and plastic contains only conductors?
No, they do not.
Which is the only president NOT to reside in the white house?
George Washington
Where does your tongue generally detect sweet tastes?
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.
What prevents too much toner from sticking to the cylinder surface in a laser printer?
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.
