When a dielectric ( insulator) is kept between the two plates of a charged condenser, the atoms or molecules are polarised due to shifting of + nucleus towards negative plate and negative electrons towards positive plate of the condenser. Naturally, any dielectric contains certain defects like grain boundaries, voids, dislocations etc. The migrating charges accumulate at these sites creating additional polarization. This polarization is called space charge polarization. The charges accumulate at the interfaces of the dielectric and condenser plates is called inter-facial polarization, is also one kind of space charge polarization.
No, Child-Langmuir's law assumes space charge-limited conditions, meaning the motion of charges is influenced by the presence of space charge. When the space charge is broken in a discharge tube, the assumptions of the law no longer hold and the law may not accurately predict the behavior of the system.
point charge (apex)
The charge density of a point charge is the amount of charge per unit volume at a specific point in space. It is typically represented by the symbol and is calculated by dividing the charge of the point charge by the volume it occupies.
The electric potential of a point charge at a specific point in space is the amount of electric potential energy per unit charge at that point. It is a measure of the work needed to move a unit positive charge from infinity to that specific point in the electric field created by the point charge.
The relationship between the electric field intensity (E), charge density (q), and permittivity of free space () is given by the equation E q / (). This equation shows that the electric field intensity is directly proportional to the charge density and inversely proportional to the permittivity of free space.

The influence extended to a surrounding space by a charge in motion is the gravitational field.
The cathode space charge is determined by the voltage on the filament.
In a semiconductor, the charge concentrates at the bounds of the space charge region(depletion layer).

Whoa. Slow down. There's no such thing as "the charge of an electric field". The "field" is what goes on in the space around a charge. The characteristics of the field ... like whether it attracts or repels another charge, and how strongly, and in what exact direction ... depend on the magnitude of the charge, and on its physical shape and size. The charge is the charge. That's what causes the characteristics of the space around it. The characteristics of the space around it have no effect on the charge. An electron down in the core of the sun has exactly the same charge as an electron has in a lightning bolt, in a glass of water, in the huge electric current in a high-voltage power transmission line, or in the soft skin of a tiny newborn's tush.

This gas envelope is likely the object's atmosphere. It plays a crucial role in protecting the object from space debris and radiation, and helps regulate its temperature. Additionally, it may interact with the surrounding space environment, such as solar wind.
