The AC Volt

"In the U.S., the DC volt is legally defined by the Josephson array - a super conducting quantum device with a highly repeatable output voltage. (The DC Volt, Nuts & Volts, Jan. '97.) Banks of standard cells and temperature-stabilized Zener diode references are used by the National Institute of Science and Technology (NIST) to calibrate DC meters for scientific and industrial customers. So how is the AC volt defined? As it turns out, there is no 'standard' AC volt in the same way there is a standard DC volt. Instead, the AC volt is defined by conversion to DC and comparison with a DC voltage standard ..." http://www.nutsvolts.com/magazine/article/the-ac-volt
