An apparatus which may be of similar construction with the silver voltameter (see Voltameter, Silver), but in which a copper anode and a solution of copper sulphate are substituted for the silver anode and silver nitrate solution. One coulomb corresponds to .329 milligram or .005084 grain of copper deposited. It is not accepted as of [...]

In general an apparatus for determining the quantity of electricity passing through a conductor by measuring the electrolytic action it can perform.

Electricity of low potential difference and large current intensity; electricity such as produced by a voltaic battery; current or dynamic electricity as opposed to static electricity.

The potential difference developed by contact of different conductors. It is the basis of the contact theory, q. v., of electricity, although it may be accepted as the expression for a condition of things by those who reject the above theory. This potential difference is slight when the conductors are separated, but it is calculated [...]

A term used in electro-therapeutics or medical electricity to indicate an alternating battery current. Synonym–Alternative current.

This adjective is used to qualify a great many things appertaining to or connected with current electricity. It is derived from Volta, the inventor of the voltaic battery, and now tends to displace the term “galvanic,” formerly in general use.

The voltage or potential difference at the terminals of an electric current generator, such as a dynamo, as distinguished from the total electro-motive force of the dynamo or generator. In batteries the distinction is not generally made in practice; the total electro-motive force of the battery is made the basis of calculations.

Potential difference or electro-motive force expressed in volts; as a voltage of 100 volts. Thus voltage may express the electro-motive force absorbed in a conductor, while electro-motive force is a term generally applied where it is produced, evolved or present in the object. The term voltage of a lamp expresses simply the volts required, but [...]

The practical unit of electro-motive force or potential difference. It may be referred to various data. An electro-motive force of one volt will cause a current of one ampere to flow through a resistance of one ohm. A condenser of one farad capacity charged with one coulomb will have a rise of potential of one [...]

A colloquial or trade name for zinc sulphate (Zn SO4).
