An effect produced upon the plates of a voltaic battery, or the electrodes in an electrolytic cell, by the deposition upon them of the gases liberated by the action of the current.
As it originally streamed from voltaic batteries, the electric current had always a single direction; it was, to use a familiar phrase, a direct current.
Inventors took great pains in devising apparatus to convert these alternating pulses into a direct current such as that yielded by a voltaic battery.
We stop the heating process by joining the two plates with a wire through which now passes an electric current, our simple apparatus now forming a common voltaic cell.

Mr. Mitchell, in his useful little work on natural philosophy, proposes the following cheap and easy method of constructing a Voltaic Pile.
Cheap and Easy Method of constructing a Voltaic Pile.
The adjective voltaic is synonymous with galvanic, as voltaic or galvanic cell, voltaic or galvanic current.
The unit of electrical pressure or electromotive force is called the volt, and takes its name from Volta, the great founder of the science of galvanic or voltaic electricity.
Alessandro Volta, a professor of natural philosophy at Pavia, Italy, was, it must be said, the founder of the science of galvanic or voltaic electricity.
I shocked my mother twice--first with the voltaic pile that I had constructed, and again when she found out where the metal plates came from.
We measure this pressure by a unit called the "volt," named for Volta, the inventor or discoverer of the voltaic battery.
There are other forms, or at least one other form that does not depend upon the length of the voltaic arc formed when the electrodes are separated.
The placing of two or three pieces of metal one above another with a moist substance between them will create a voltaic battery.
It may be presumed in this case that the Voltaic circuit had by some fault in the arrangement been interrupted.
Voltaic electricity is excited upon combinations of perfect and imperfect conductors, and is only transmitted by perfect conductors, or imperfect conductors of the best kind.
To those the least acquainted with the principles of Voltaic action, it was only necessary to state the proposition, in order to command their assent to its truth.
Ash noticed, for the first time, a phenomenon which was subsequently referred to the action of a simpleVoltaic circuit.
At first, he thought of using a Voltaic battery; but this could hardly be applicable in practice.
We have never constructed a Voltaic battery of sufficient power," was the answer.
I have now concluded a review of those admirable researches which led Sir Humphry Davy to suggest and mature a plan for arresting the corrosion of the copper sheathing of vessels by Voltaic action.
In the equatorial regions, on the contrary, upright wheels placed parallel to the equator will originate a voltaic circuit, and waterfalls will naturally become electric.
In the voltaic circuit, again, we cannot have one current without its opposite.
There was an instantaneous effect at the closing and breaking of the voltaic circuit; electric inductions appeared when the two wires were moved to and from one another; but these are phenomena of a different class.
Some Relations of Heat toVoltaic and Thermo Electric Action of Metals in Electrolysis.
The experiments described in this paper throw considerable light upon the real cause of the voltaic current.
The first experiment which he has recorded was the construction of a voltaic pile with seven halfpence, seven disks of sheet zinc, and six pieces of paper moistened with salt water.
For example, the simple voltaic cell and the gravity cell have approximately equal voltages, but the current produced by the voltaic cell is stronger than that produced by the gravity cell.
But in the year 1800, electricity in the form of a weak current was obtained by Volta of Italy in a very simple way; and even now our various electric batteries and cells are but a modification of that used by Volta and called a voltaic cell.
The hydrogen formed by the chemical action of the dilute sulphuric acid on the zinc moves toward the copper electrode, as in the simple voltaic cell.
When the poles of a simple voltaic cell are connected by a wire, the current thus produced slowly diminishes in strength and, after a short time, becomes feeble.
This is because the current meets more resistance within the gravity cell than within the voltaic cell.
We know that, by means of voltaic electricity or induction, we can crystallize a large number of substances.
The voltaic current was now, for the first time, observed to produce a deviation of the magnetic needle in different directions, and in different degrees, according to the relative situation of the wire and needle.
No experiment appears, however, to have been made to determine the question until 1820, when Oersted placed a magnetic needle within the influence of a wire connecting the extremities with a voltaic battery.
Into the cell are dipped two very thin platinum wires, and these are connected by other wires with a small voltaic battery.
The lines D he found to he considerably strengthened by the passage of the solar light through the voltaic arc.
He did not extend his observations beyond the voltaic arc; he did not offer any explanation of the lines of Fraunhofer; he did not arrive at any conception of solar chemistry, or of the constitution of the sun.
Before you is an instrument--a small voltaic battery--in which zinc is immersed in a suitable liquid.
My second example of the action of crystallizing force is this: By sending a voltaic current through a liquid, you know that we decompose the liquid, and if it contains a metal, we liberate this metal by electrolysis.
He employed a voltaic current to heat his platinum, and he studied, by means of a prism, the successive introduction of the colours of the spectrum.
The rust is cleared away by voltaic action; the iron forms the negative pole, the zinc the positive of a voltaic cell, in which the water is resolved into its constituents, viz.
The brilliant results which chemistry has obtained by means of the Voltaic battery, have occupied all observers, and turned attention for some time from the examinations of the phenomena of vitality.
The action of the fish on the human organs is transmitted and intercepted by the same bodies that transmit and intercept the electrical current of a conductor charged by a Leyden jar, or Voltaic battery.
We cannot discharge at will either a torpedo or a gymnotus, as we discharge at will a Leyden jar or a Voltaic battery.
To be aware of the difference that exists between the sensation produced by the Voltaic battery and an electric fish, the latter should be touched when they are in a state of extreme weakness.
He went on to show that the total heat produced in any voltaic circuit was proportional to the electromotive force E of the battery and to the number of equivalents electrolysed in it.
Thin platinum wire was rendered incandescent by a voltaic current; a small incandescent electric lamp would now be found more satisfactory.
In this paper he showed that the heat produced by currents generated by magneto-electric induction followed the same law as voltaic currents.
The positive plate of a voltaic or electrolytic cell.
In fact, bass will not be induced to decently decease by any civilized process short of a powerful shock from a voltaic pile administered in the region of their medulla oblongata.
Of course, one cannot be expected to carry about a voltaicpile and go hunting for the medullary recesses of a savage and turbulent fish.
