Has anybody used a standard cell within the last 12 months? If so, for
what?
Hi, Alex,
My guess is that relatively few people have.
I think that NIST may still maintain a bank of standard cells, but that
the Josephson frequency voltage quotient
(2e/h) = 4.8359767(14) x10^14V^-1 has replaced the use of standard cells
almost everywhere.
