Plasma conductivity

Description

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Electrical conductivity or specific conductance is the reciprocal of electrical resistivity, and measures a material’s ability to conduct an electric current.
The electrothermal instability (also known as the ionization instability ) is a magnetohydrodynamic (MHD) instability appearing in magnetized non-thermal plasmas used in MHD converters. In a non-equilibrium ionized gas with high Hall parameter the scalar electrical conductivity is depended on the electron density and the electron-heavy particles collision frequency.
