Voltameter

a device for measuring the quantity of electricity according to the chemical activity of a current. The voltameter is a platinum crucible (cathode) filled with a 20-40 percent water solution of silver nitrate into which a rod or disk of chemically pure silver (anode) is submerged. When an electric current is passed through the voltameter, the silver is deposited on the inner surface of the crucible (there is also a separating glass for particles of silver and accidental impurities which precipitate out mechanically). The quantity of electricity is determined according to the weight of the crucible before the experiment gl and after the experiment g₂:

(m is the electrochemical equivalent). The voltameter is rarely used, having been practically replaced by ampere-clock calculators. If the time the electric current takes to pass through the voltameter is known, it is possible to determine its average value.
