In summary, when a conductor is exposed to an electric field, the electrons and kernels within the conductor experience a separation. The degree of separation depends on the intensity of the field. This separation is not quantum and is not evenly distributed, with one end having no electrons and the other having evenly distributed electrons. The displacement of the electrons creates a counter electric field to cancel out the external field within the conductor. This applies to both conductors and dielectrics.

When a conductor is made to experience a field, there's a separation of kernels and electrons...now depending on the intensity of this fields, the degree of separation varies.

Now is this separation quantum?...I mean at one end there're absolutely no electrons, while in the other we have evenly distributed electrons.

By kernels, I presume you mean the fixed positive charges in the conductor that do not move.. When the wire (conductor) is in an electric field (aligned along the E field), there is a very small displacement of the electrons in the conductor to produce a slight electric dipole moment of the conductor. The displacement of the electrons produces a counter electric field in the conductor such that there is no net electric field (voltage gradient) in the conductor. Since the electrons are primarily the conduction electrons which are free to move, the separation is not quantized. This is also true if the conductor is a dielectric, because the valence electrons are displaced.

No no...I'm not talking about a wire...consider a plate immersed in a field.
 

1. What is charge separation?

Charge separation is the process of separating positive and negative charges within a material, resulting in an overall electric dipole moment. This can occur when an electric field is applied to a material, causing the positively charged particles to move in one direction and the negatively charged particles to move in the opposite direction.

2. How does electric field intensity affect charge separation?

The intensity of an electric field is directly proportional to the amount of charge separation that occurs. A stronger electric field will result in a greater separation of charges, while a weaker field will result in less separation.

3. What are the practical applications of charge separation?

Charge separation plays a crucial role in many technologies, such as capacitors, batteries, and solar cells. It is also involved in the generation of lightning and is utilized in particle accelerators.

4. Can charge separation be reversed?

Yes, charge separation can be reversed by removing the electric field. The charges will then begin to move back towards each other, resulting in an overall neutralization of the material.

5. How is the direction of charge separation determined?

The direction of charge separation is determined by the direction of the electric field. Positive charges will move in the direction of the field, while negative charges will move in the opposite direction.
