Sentence Examples


  • ELECTRICAL (or [[Electrostatic) Machine]], a machine operating by manual or other power for transforming mechanical work into electric energy in the form of electrostatic charges of opposite sign delivered to separate conductors.
  • In the Nalder ohmmeter the electrostatic principle is employed.
  • It has in fact been found, with the very great precision of which optical experiment is capable, that all terrestrial optical phenomenareflexion, refraction, polarization linear and circular, diffraction - are entirely unaffected by the direction of the earth's motion, while the same result has recently been extended to electrostatic forces; and this is our main experimental clue.
  • Electrostatic instruments, however, take up no power and hence cost nothing for maintenance other than wear and tear of the instrument.
  • Electrostatic voltmeters are also liable to have their indications disturbed by electrification of the glass cover of the instrument; this can be avoided by varnishing the glass with a semi-conducting varnish so as to prevent the location of electrostatic charges on the glass.
