Electrode in a sentence

When you plug in your electric car or phone, the electricity provided by the outlet from the battery’s positive electrode into its negative electrode.

Lithium-ion batteries consist of a positive electrode, the cathode, a negative electrode, the anode, and an electrolyte, as well as auxiliary components such as terminals and casing.

A combined glass electrode has an in-built reference electrode.

A new electrode replaces the old one, but a sizeable piece of the old electrode remains.

Anode and cathode in electrochemical cells Configuration of the electrode An electrode in an electrochemical cell is referred to as either an anode or a cathode (words that were coined by William Whewell at Faraday's request).

At high pH the glass electrode may be affected by "alkaline error", because the electrode becomes sensitive to the concentration of cations such as Na + and K + in the solution.

Choice of suitable electrode depends on chemical reactivity between the electrode and electrolyte and manufacturing cost.

Complicating issues is the challenge in cooling the central electrode; any fusor producing enough power to run a power plant seems destined to also destroy its inner electrode.

Consumable electrode processes such as shielded metal arc welding and gas metal arc welding generally use direct current, but the electrode can be charged either positively or negatively.

Conversely, if the measured potential is negative, the electrode is more oxidizing than the SHE (such as Zn in ZnSO 4 where the standard electrode potential is −0.76 V).

For example, if an electric field is placed across a solution of Na + and Cl − (and conditions are right) the sodium ions move towards the negative electrode (cathode), while the chloride ions move towards the positive electrode (anode).

If an electrical potential (voltage) is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons.

In 1838, Michael Faraday passed a current through a rarefied air filled glass tube and noticed a strange light arc with its beginning at the cathode (negative electrode) and its end are at the anode (positive electrode).

In a cell, there will be an electrode potential for the cathode, and an electrode potential for the anode.

In a full electrochemical cell, species from one half-cell lose electrons ( oxidation ) to their electrode while species from the other half-cell gain electrons ( reduction ) from their electrode.

It uses a two-layer grid of electrodes to measure finger movement: one layer has vertical electrode strips that handle vertical movement, and the other layer has horizontal electrode strips to handle horizontal movements.

Measurement Three-electrode setup for measurement of electrode potential.

Metal water pipe used as grounding electrode A grounding electrode conductor (GEC) connects one leg of an electrical system to one or more earth electrodes.

Standard electrode potential main To allow prediction of the cell potential, tabulations of standard electrode potential are available.

The electrode holder holds the electrode as it slowly melts away.
