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.
Metals are good conductors because they consist of a lattice of atoms with free electrons. The free electrons allow a current to flow through. When a negative charge is applied at one end, the electrons are repelled from the negative charge, and move towards the other end.
Assuming you do not mean the plastic bags at the supermarket checkout that cost nothing, then you may be referring to free charge carriers in electical conductors and semiconductors, which are electrons in metallic conductors and electrons or "holes" in semiconductors. Now what was the question?
Good conductors are those with heaps of free electrons. Summary: Good conductors usually have metallic bonds, where there are free electron in a lattice of a material, conducting charge.
Under normal circumstances, a conductor has no overall charge. Even though there are large numbers of free electrons available as charge carriers, for each free electron there is a corresponding proton within the atoms that make up the conductor. With equal numbers of protons and electrons, there is no overall charge.
when a capacitor is connected to earth the potential of capacitor becomes zero. as a result all the charge residing on the conductors of a capacitor passes away and the final charge on capacitor becomes zero
If charge is transferred to the object at a given location, that charge is quickly distributed across the entire surface of the object. The distribution of charge is the result of electron movement.
No, the charge held by a solid metal sphere and a hollow sphere of the same diameter would be the same. In both cases, the charge resides on the outer surface of the sphere due to the principle of electrostatic equilibrium.
E field does not exist within the conductor, because the charge exists on the surface. This is not true for non conductors.
yes
Electrical Conductors!
It is easier to charge no-conductors with the hands because the charge generated will not be discharged through our bodies.
some one everywhere (slaves)
You, cant charge them everywhere :)
Either one can acquire a static charge.
A nuetron has no charge and resides in the nucleus of an atom along with protons that have a positive charge. Electrons have a negative charge and are in the electron shells around the nucleus.
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.
They contain delocalised electrons which can move and carry charge.
