In this way he discovered the electrochemical series, and the law that the electromotive force ( emf ) of a galvanic cell, consisting of a pair of metal electrodes separated by electrolyte, is the difference between their two electrode potentials ( thus, two identical electrodes and a common electrolyte give zero net emf ).

Initially he experimented with individual cells in series, each cell being a wine goblet filled with brine into which the two dissimilar electrodes were dipped.

It consists of two electrodes: one made of zinc, the other of copper.

If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode ( the electrode connected to the negative terminal of the voltage supply ).

The voltage applied between the two electrodes of the tubes, generated by an induction coil, was anywhere between a few kilovolts and 100 kV.

An electron avalanche happens between two unconnected electrodes in a gas when an electric field exceeds a certain theshold.

A vacuum tube diode, now used only in some high-power technologies and by enthusiasts, is a vacuum tube with two electrodes, a plate ( anode ) and filament ( cathode ).

*** Dielectric barrier discharge, the electrical discharge between two electrodes separated by an insulating dielectric barrier

Electrochemical cells have two conductive electrodes ( the anode and the cathode ).

The galvanic cell uses two different metal electrodes, each in an electrolyte where the positively charged ions are the oxidized form of the electrode metal.

A concentration cell is an electrochemical cell where the two electrodes are the same material, the electrolytes on the two half-cells involve the same ions, but the electrolyte concentration differs between the two half-cells.

For example an electrochemical cell, where two copper electrodes are submerged in two copper ( II ) sulfate solutions, whose concentrations are 0. 05 M and 2. 0 M, connected through a salt bridge.

In PEF processing, a substance is placed between two electrodes, then the pulsed electric field is applied.

Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, and two polarizing filters, the axes of transmission of which are ( in most of the cases ) perpendicular to each other.

In a twisted nematic device ( still the most common liquid crystal device ), the surface alignment directions at the two electrodes are perpendicular to each other, and so the molecules arrange themselves in a helical structure, or twist.

A Leyden jar, or Leiden jar, is a device that " stores " static electricity between two electrodes on the inside and outside of a glass jar.

A vacuum tube consists of two or more electrodes in a vacuum inside an airtight enclosure.

He must rearrange matters so that two performers do not bump into each other.

To you, for instance, the word innocence, in this connotation, probably retained its Biblical, or should I say technical sense, and therefore I suppose I must make myself quite clear by saying that I lost -- or rather handed over -- what you would have considered to be my innocence two weeks before I was legally entitled, and in fact by oath required, to hand it over along with what other goods and bads I had.

To almost two generations of Americans it must have seemed as though the existence of Mr. Sam coincided with that of the House.

Of course, some of the credit for the sale boost must be given to improvement in the weather and to the fact that Easter comes more than two weeks earlier than in 1960.

You may stay as long as you wish, of course, but if arranging for the care of the girls must take time into account, I think a day or two should be enough to finish our business in ''.

We must ask ourselves which of the two alternatives will help the commuter -- the two-way B. & O. - C. & O. merger, or the three-way New York Central - B. & O. - C. & O. merger.

When more than two figures are separated by subtraction symbols the subtraction must be carried out from the left to right if the result is to be correct.

From here you can easily include a side trip to the old whaling port of Nantucket, Massachusetts, which looks just as it must have two centuries ago.

You danced two tangos and a paso doble, which must have been fairly enervating in that milieu.

We must now show that on some component of the graph there exist two points for which the corresponding diagonal points in the C-plane are on opposite sides of C.

Moreover, if Af and Af are two planes intersecting in a line l, tangent to Q at a point P, the two free intersections of the image curves Af and Af must coincide at P', the image of P, and at this point Af and Af must have a common tangent l'.

But if no two lines of the regulus of multiple secants of **zg can intersect, then the regulus must be quadratic, or in other words, **zg must be either a Af or a Af curve on a nonsingular quadric surface.

In addition, two other differences in the two types of sections must be noted.

But first, we must define two terms so that their meaning will be clearly understood: form -- any unique sequence of alphabetic characters that can appear in a language preceded and followed by a space ; ;

But before turning to this example, we must distinguish two subtypes of analysis, both of which belong to the single-step type rather than to the double-step type.

To become an orthodontist, a man must first be licensed by his state as a dentist, then he must spend at least two years in additional training to acquire a license as a specialist.

The possibility has to be ruled out that the medium's ESP may tap the memory of the sitter, and to do this, the two central characters in this drama must be separated.

To be sure, in tool-and-die work and in the building trades, the first job must be often on an apprentice basis, but two years of half-time vocational training enables the young man thus to anticipate one year of apprentice status.

They, and the two large fans which I could dimly see as daylight filtered through their vents, down at the far end of the hall, could be turned on by a master switch situated inside the office.

It'll probably be at least an hour or two before I can check back with you.

I had seen two of them and we would soon be in another city-wide, joyous celebration with romance in the air ; ;

In two minutes the body of Tilghman's former comrade, who had been killed by Blue Throat in a gambling brawl the previous night, was carried into the town's funeral parlor to be prepared for decent burial.

These two were going to be easy pickins.

( There are two receivers in case one should be dropped and damaged.

The ideal home, they agreed, would be a small private house or a city apartment of four to five rooms, just enough for a family consisting of husband, wife, and two children.

Even two decades ago in Go Down, Moses Faulkner was looking to the more urban future with a glimmer of hope that through its youth and its new way of life the South might be reborn and the curse of slavery erased from its soil.

the two may in fact be identical.

Whatever pole of this contrast one emphasizes and whatever the tension between these two approaches to understanding the artistic imagination, it will be readily seen that they are not mutually exclusive, that they belong together.

But people can't be made to integrate, socialize ( the two are inseparable by Southern standards ) by law.

They may even enroll a colored student or two for show, though he usually turns out to be from Thailand, or any place other than the American South.

Of these there are surely few that would be more rewarding discoveries than Verner Von Heidenstam, the Swedish poet and novelist who received the award in 1916 and whose centennial was celebrated two years ago.

If I now risk some comparisons with Sons And Lovers let it be clear that I am not comparing the two works or judging their merits ; ;

`` the matters to be considered are obviously of a grave character, and I therefore respectfully request that the hearing be postponed for two weeks in order that I might make adequate preparation ''.

It purported to be a reasonably serious attempt at a treatment of jazz musicians, their aims, their problems -- the tug-of-war between the `` pure '' and the `` commercial '' -- and seemed a promising vehicle, for the two men shared a common interest in jazz.

It so happened that sports writer Arthur Robinson got out of the hospital that morning after promising his doctor that he be back in an hour or two to continue his convalescence.

`` But if there is no line, how can there be two countries??

Seeing their hesitation, I said, `` Well, until I have permission to enter Germany, or a visa to re-enter France, I shall be obliged to remain here on the line between two countries '', whereupon I moved to the side of the road, parked my backpack against the small guardhouse on the sidewalk, sat down, took out my typewriter, and began typing the above conversation.
