Definition of electrometer in English:



  • An instrument for measuring electrical potential without drawing any current from the circuit.

    • ‘To detect the small resulting current, she used an electrometer of an excellent design created by Pierre and his physicist brother, Jacques, some years earlier.’
    • ‘Hertz generated cathode rays inside an apparatus that included an electrometer to measure the electrical charge of the rays.’
    • ‘Shortly after Antoine Becquerel and others developed the electrometer, John Mothée Gaugain made the first precise measurements of pyroelectric charges in 1859.’
    • ‘The electrodes from each specimen measured were connected to an electrometer, which in turn was connected to a Pentium PC, which yielded a printout of the measurement.’
    • ‘Protein was added to both sides of the membrane, and the increase of the membrane conductance due to insertion of pores was observed with the electrometer.’
    • ‘The studies were done using a physical properties measurement system and electrometers at the Los Alamos National Laboratory.’
    • ‘Rather, he was standing still, carefully reading a delicate instrument inside his apartment, when lightning struck an iron rod outside to which the electrometer was connected.’
    • ‘Cables aside, he carried out research into atmospheric electricity, inventing the water-dropping collector, and vastly improving the electrometer.’
    • ‘Voltage output from the electrometer was sent to a chart recorder and collected on computer disk via a data acquisition system.’
    • ‘Electrostatic methods are normally used, such as the field mill, which measures induced electric charge, or an ultra-high-impedance electrometer voltmeter.’
