resistivity

plasmapy.physics.transport.braginskii.resistivity(T_e, n_e, T_i, n_i, ion_particle, m_i=None, Z=None, B=<Quantity 0. T>, model='Braginskii', field_orientation='parallel', mu=None, theta=None, coulomb_log_method='classical') -> Unit("m Ohm")

Calculate the resistivity.

Notes

The resistivity here is defined similarly to solid conductors, and thus represents the classical plasmas’ property to resist the flow of electrical current. The result is in units of ohm * m, so if you assume where the current is flowing in the plasma (length and cross-sectional area), you could calculate a DC resistance of the plasma in ohms as resistivity * length / cross-sectional area.

Experimentalists with plasma discharges may observe different V = IR Ohm’s law behavior than suggested by the resistance calculated here, for reasons such as the occurrence of plasma sheath layers at the electrodes or the plasma not satisfying the classical assumptions.
