The effect of an electrostatic energy (in the geometrical capacitance
approach) on a persistent current is considered. It is shown that at high temperatures
the current amplitude shows periodic dips as a function of the potential difference
between a ring and a reservoir. These dips correspond to a lift of the Coulomb
blockade. In a minimum of a dips a current is periodic in a magnetic flux with
a period 
at any temperatures.
