An electrometer is an electrical instrument for measuring electric charge or electrical potential difference. [1] There are many different types, ranging from historical handmade mechanical instruments to high-precision electronic devices.
A Lippmann electrometer is a device for detecting small rushes of electric current and was invented by Gabriel Lippmann in 1873. [1] The device consists of a tube which is thick on one end and very thin on the other.
The E-Meter (also electropsychometer and Hubbard Electrometer) is an electronic device used in Scientology that allegedly "registers emotional reactions". [1] After claims by L. Ron Hubbard that the procedures of auditing , which used the E-Meter, could help heal diseases, the E-Meter became the subject of litigation.
An electroscope can only give a rough indication of the quantity of charge; an instrument that measures electric charge quantitatively is called an electrometer. The electroscope was the first electrical measuring instrument. The first electroscope was a pivoted needle (called the versorium), invented by British physician William Gilbert around ...
Lippmann's electrometer consists of a tube of ordinary glass, 1 metre long and 7 millimetres in diameter, open at both ends, and kept in the vertical position by a stout support. The lower end is drawn into a capillary point, until the diameter of the capillary is .005 of a millimetre.
The electrometer measures charge with respect to ground, so it requires a connection to ground during use. [13] It has a ground wire, usually colored black, ending in a clip which should be attached to a metal ground during use. The experimenter should avoid excessive movement during the experiment. [13]
Electrometer is often used to reconfirm the phenomenon of contact electricity leading to triboelectric sequences. Torsion balance used by Coulomb to establish a relation between charges and force, see above. For the ranges of charge values see: Orders of magnitude (charge)
