| 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. |
| 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. |
| The dye was iontophoretically injected by current pulses of short duration, generated by the electrometer. |
| Cables aside, he carried out research into atmospheric electricity, inventing the water-dropping collector, and vastly improving the electrometer. |
| The use of an electrometer or galvanoscope for sensing magnetic field or electric fields are well known. |
| Hertz generated cathode rays inside an apparatus that included an electrometer to measure the electrical charge of the rays. |
