The Watt Balance Balance Gravity Force with EMF Find value as long as h, Planck’s Constant Physics Animation (if it works)

Measurements: Voltage Hg Battery Stabilized I-Source Zener Diode Josephson Array Voltage Determine f with GPS Atomic clock Measurements: Velocity 3 HeNe Laser systems give v in addition to z Easily referenced to Meter st in addition to ard: HeNe = 632.99139822 nm Measurement: Current Use DVM (Josephson ref.) to measure V across R Get R via Quantum Hall Effect DVM

Measurement: Gravity Easy to reference gravity! Use nearby gravimeter < 10 meters away Reference with HeNe, GPS When scale is balanced Watt-Balance UC Arrington, Debbie Sacramento Bee, The Features Reporter www.phwiki.com
