84Method of image charges — The method of image charges (also known as the method of images and method of mirror charges) is a basic problem solving tool in electrostatics. The name originates from the replacement of certain elements in the original layout with imaginary… …
85electron tube — an electronic device that consists, typically, of a sealed glass bulb containing two or more electrodes: used to generate, amplify, and rectify electric oscillations and alternating currents. Also called electronic tube. Cf. gas tube, vacuum tube …
86Defining equation (physics) — For common nomenclature of base quantities used in this article, see Physical quantity. For 4 vector modifications used in relativity, see Four vector. Very often defining equations are in the form of a constitutive equation, since parameters of… …
87Langmuir probe — A Langmuir probe is a device named after Nobel Prize winning physicist Irving Langmuir, used to determine the electron temperature, electron density, and electric potential of a plasma. It works by inserting one or more electrodes into a plasma,… …
88Plasma (physics) — For other uses, see Plasma. Plasma lamp, illustrating some of the more complex phenomena of a plasma, including filamentation. The colors are a result of relaxation of electrons in excited states to lower energy states after they have recombined… …
89Electrostatics — For a less technical introduction, see Static electricity. Electromagnetism …
90List of physical quantities — This is a list of physical quantities.The first table lists the base quantities used in the International System of Units to define the physical dimension of physical quantities for dimensional analysis. Note that the angle and solid angle are… …
