What are free and bound charges in electrostatics?
A free charge is not bound to the nucleus and can have any energy from zero. A bound charge, on the other hand, is bound to the nucleus and can have only quantized energies. The energy possessed by it is both potential and kinetic in nature with potential energy being greater always.
What is bound charge in electricity?
Definition of bound charge : the portion of the electrical charge on a conductor that because of the inductive action of a neighboring charge will not escape to the earth when the conductor is grounded.
What is the charge of a free electron?
Electron
| Hydrogen atomic orbitals at different energy levels. The more opaque areas are where one is most likely to find an electron at any given time. | |
|---|---|
| Composition | Elementary particle |
| Mean lifetime | stable ( > 6.6×1028 yr) |
| Electric charge | −1 e −1.602176634×10−19 C −4.80320451(10)×10−10 esu |
What is electrostatic charge simple?
Static electricity or an electrostatic charge is a deficiency or excess of electrons which occurs on ungrounded or insulating surfaces. It is produced by triboelectric charges, charges that are generated by friction between two surfaces, such as the movement of paper through a copier or printer.
What is meant by free and bound currents?
Bound charge is simply the charge due to polarization, and the free charge is the other (i.e. non-bound) charge.
What is bound charge density?
Bound charge is the unit normal vector to the surface. Taking infinitesimals: and dividing by the differential surface element dS gives the bound surface charge density: where P is the polarization density, i.e. density of electric dipole moments within the material, and dV is the differential volume element.

What is the relationship between free charge and induced charge?
The induced surface charge produces an induced electrical field that opposes the field of the free charge on the capacitor plates. The dielectric constant of a material is the ratio of the electrical field in vacuum to the net electrical field in the material.
What is bound electron?
A bound electron is one that is still considered part of the atom and is attracted to the nucleus whereas a free electron is one that absorbed enough energy from photons to completely leave the atom.
What is electrostatic simple?
Electrostatics (also known as static electricity) is the branch of physics that deals with apparently stationary electric charges. Electrostatics involves the buildup of charge on the surface of objects due to contact with other surfaces.
