f=2 e U/h
where h is the Planck constant and e is the elementary electric charge
Note 1 to entry: The AC Josephson effect also manifests itself conversely so that, when a Josephson junction is irradiated by an electromagnetic radiation of frequency f, the voltage across it can assume quantized values equal to (h/2e) n f, where n is a positive integer.
Note 2 to entry: f/U =483 597,848 416 984 Hz V-1.
Note 3 to entry: This entry was numbered 815-10-39 in IEC 60050-815:2015.
