Plasma (physics) potential in the space between charged particles, independent of how it can be measured, is called the "plasma potential", or the "space potential". If an electrode is inserted into a plasma, its potential will generally lie considerably below the plasma potential due to what is termed a Debye sheath. The good electrical conductivity of plasmas makes their electric fields very small. This results in the important concept of "quasineutrality", which says the density of negative charges is approximately equal to the density of positive charges over large volumes of the plasma (formula_6), but on the scale of the Debye length
Negative and positive rights Under the theory of positive and negative rights, a negative right is a right "not to be" subjected to an action of another person or group—a government, for example—usually in the form of abuse or coercion. As such, negative rights exist unless someone acts to "negate" them. A positive right is a right "to be" subjected to an action of another person or group. In other words, for a positive right to be exercised, someone else's actions must be "added" to the equation. In theory, a negative right forbids others from acting against the right holder, while a positive right
