✦ Synopsis

I show that the Ôintrinsic tunnellingÕ (IT) characteristics of Bi2212 and Bi2201 can be reproduced if the heating caused by Joule dissipation is the only reason for nonlinearities observed in their current-voltage characteristics. Thus, experimental normal state c-axis resistance R N ðT Þ and NewtonÕs Law of Cooling provide a natural explanation of the divergency between the results obtained with conventional spectroscopy and those derived from IT.
