0 a measure of the electrical resistance of a substance
1 a measure of the electrical resistance of a substance
Its form is determined by the fact that the main linear regulating factor was supposed to be the resistivity.
We believe, however, that basic features of anomalous resistivity have not always been properly taken into account.
Only then can a reliable prediction be made for the time scale of the current-current interaction process with realistic resistivities.
In the magnetically dominated regime, the eddy resistivity is found to be negative definite, leading to large-scale instabilities.
Resistivity of this form is due to wave-particle interactions between the dust and ion fluids.
We again set the viscosity = 0, but we retain a finite resistivity required for tearing modes.
However, if the perfectly conducting wall is replaced by one with finite resistivity the plasma is again unstable.
The anomalous resistivity must be generated by the micro-instability in particle dynamics.
