It has been suggested by various authors over the past 15 years, and also recently, that in tokamaks the perpendicular resistivity η⊥ is between 102and 103times the parallel (Spitzer) resistivity. Here it is shown that on the contrary the measurements on the FTU tokamak [Proceedings of the 16th Symposium on Fusion Technology, London, 1990 (North-Holland, Amsterdam, 1991), Vol. 1, p. 218] are consistent with η⊥/η∥=2 when the extended neoclassical theory is used (which is preferable to the conventional neoclassical theory for reasons which are here reviewed). © 1992 American Institute of Physics.
