Combining equations (A-7a) and (A-8a) one has

The first order a-c. convection current density is given by 



qi = Poi^'i + piui (A-10) 



which, by combining with (A-7a) and (A-8b), becomes 



j{k/r]oKpoi/meo)E^

Similarly

[f we now define

 Equations (11) and (12) become 



(Z - B,) 

 Thus equation (A-6) becomes 



(A-11)
