This is why we have to adopt a totally different approach that satisfies the conditions set up before. So, using the two equations for
and 
mentioned above, we will try to apply the law of conservation of energy - that should still be valid - and calculate h.
The attentive reader will certainly have realized that the above calculations were inconsistent with respect to the applicable measurement system . Now, we decide to use the Gaussian CGS system, first writing down the two equations for
and :
XXVII
XXVIII
where 
is the supercurrent and ns the concentration of the electrons involved in superconduction. First, we face the task of rewriting the two equations for one electron. In doing so, for the term we will proceed as usual:
XXVIX
Thus, we view at our path - as agreed upon - for example from direction 1 and select - for the path taken by the electron - the entire path the electron draws on a projection perpendicular to direction 1 during one revolution. We designate this term as 
. Now let's turn to the term ns:
| ns = | number of electrons involved in the superconduction | = | n |
