Stray capacitances in the watt balance operation: electrostatic forces

  title={Stray capacitances in the watt balance operation: electrostatic forces},
  author={Danilo Quagliotti and G Mana},
  pages={S72 - S79}
In a watt balance, stray capacitances exist between the coil and the magnet. Since the electric current flowing in the coil creates a difference in electric potentials between the coil and magnet, their electrostatic interactions must be taken into account. This paper reports the results of a finite element analysis of the forces acting on the coil.

The watt or Kibble balance: a technique for implementing the new SI definition of the unit of mass

The redefinition of the SI unit of mass in terms of a fixed value of the Planck constant has been made possible by the Kibble balance, previously known as the watt balance. Once the new definition

Progress on accurate measurement of the Planck constant: Watt balance and counting atoms

The Planck constant h is one of the most significant constants in quantum physics. Recently, the precision measurement of the value of h has been a hot issue due to its important role for the



The watt-balance operation: a continuous model of the coil interaction with the magnetic field

In the watt-balance experiments, separate measurements of the magnetic and electromotive forces in a coil in a magnetic field enable a virtual comparison between mechanical and electric powers to be

The watt-balance operation: magnetic force and induced electric potential on a conductor in a magnetic field

In a watt-balance experiment, separate measurements of magnetic force and induced electric potential in a conductor in a magnetic field allow for a virtual comparison between mechanical and

Alignment of the NPL Mark II watt balance

To reach uncertainties in the region of 1 part in 108 a moving-coil watt balance not only requires the accurate measurement of voltage, resistance, velocity, mass and the acceleration due to gravity

Reconciling Planck constant determinations via watt balance and enriched-silicon measurements at NRC Canada

The next revision to the International System of Units will emphasize the relationship between the base units (kilogram, metre, second, ampere, kelvin, candela and mole) and fundamental constants of

A measurement of the Planck constant

The advent of the Josephson effects and the more recently discovered quantized Hall resistance1 has led to rapid progress in the measurement of certain combinations of the fundamental constants, so

Towards the redefinition of the kilogram: a measurement of the Planck constant using the NPL Mark II watt balance

After the elimination of significant mechanical problems, the NPL Mark II moving-coil watt balance made an initial series of measurements in the period from October 2006 to March 2007. Incremental

Determination of the Planck constant with the METAS watt balance

The METAS watt balance project was initiated slightly more than a decade ago. Over this time, the apparatus has been through an uninterrupted series of upgrades that have improved its reliability to

Counting the atoms in a 28Si crystal for a new kilogram definition

This paper concerns an international research project aimed at determining the Avogadro constant by counting the atoms in an isotopically enriched silicon crystal. The counting procedure was based on

A determination of the Avogadro Constant

We have determined Avogadro's constantNA using a direct method. The result ofNA=6.0221363×1023 mol−1 differs from the most recent CODATA value of 6.0221367×1023 mol−1 by only 0.07 ppm, the relative
