Abstract :
An indirect quantum standard of current, based on the simultaneous use of the Josephson and quantum Hall effects, may help to achieve interesting results in fundamental experiments involving the determination of the elementary electrical charge e and of the Josephson and von Klitzing constants. A feasibility study of such a measuring system is proposed.<>
