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
Positive real numbers numbers. For a given positive real number "x", the sequence {"x"} of its integral powers has three different fates: When "x" ∈ (0, 1) the limit is zero and when "x" ∈ (1, ∞) the limit is infinity, while the sequence is constant for "x" = 1. The case "x" > 1 thus leads to an unbounded sequence. formula_10 and the multiplicative inverse function exchanges the intervals. The functions floor, formula_11, and excess, formula_12, have been used to describe an element formula_13 as a continued fraction formula_14 which is a sequence of integers obtained from the floor function after the
