This quantity names a type of unstable "wall mode" in plasma confinement devices such as tokamaks. This quantity is proportional to the electron density divided by temperature raised to the three-halves power all times the Coulomb logarithm according to a formula derived by Lyman Spitzer. A diffusion equation for the magnetic field can be derived from an extension to ideal magnetohydrodynamics named for this quantity. The square root of four kT times bandwidth times this quantity gives the rms voltage of thermal noise. This quantity is the inverse of the slope of a curve which possesses a linear and a saturation region for a MOSFET. It is the inverse of a quantity equal to the ratio of current density to electric field. This quantity is added to reactance to give impedance. For 10 points, name this quantity equal to voltage divided by current according to Ohm's Law.
