1. Causing the movement of electric charges which result in the flow of electrical current.
2. Relating to or producing an electric current or electric action.
3. A reference to the passage of electricity in a current or a motion produced by it.

A list of elements arranged according to their standard electrode potentials, with noble metals; such as, gold, being positive and active metals, including zinc, being negative.

1. The pressure that causes electrons to move in an electrical circuit, measured as the amount of energy supplied by an electric current passing through a given source, as measured in volts.
2. The electric potential, or ability of electric energy to perform work.

Electromotive force is usually measured in joules per coulomb, or volts; and the higher the voltage, the greater the potential of electric energy.

Any device; such as, a storage battery, that converts some form of energy into electricity is a source of electromotive force or EMF or emf; or, a generator produces an electromotive force.

3. The difference in electric potential, or voltage, between the terminals of a source of electricity; such as, a battery from which no current is being drawn. When current is drawn, the potential difference drops below the emf value.
4. The force that causes a flow or the movement of electrons through an electrical circuit.

It is the amount of energy derived from an electric source in one second when one unit of current is passing through the source, commonly measured in volts.

Electromotive force is produced by differences in electrical charge or potential.

5. Energy per unit electric charge that is imparted by an energy source; such as, an electric generator or a battery.

When the device does work on the electric charge being transferred within itself, energy is converted from one form to another.

1. The classification of metals in the order of their electrode potentials.
2. A serial arrangement of metallic elements or ions according to their electrode potentials determined under specified conditions; the order shows the tendency of one metal to reduce the ions of any other metal below it in the series.
3. A series in which the metals and other substances are listed in the order of their chemical reactivity or electrode potentials, the most reactive at the top and the less reactive at the bottom.
4. A tabulation on which various substances; such as, metals or elements, are listed according to their chemical reactivity or standard electrode potential.

It is usually ordered with increasing standard electrode potentials (most negative on top).

For metals, the order indicates the tendency to spontaneously reduce the ions of any other metal below it in the series.

During electrolytic reduction of cations (for example, electroplating) an element lower in the series (more positive) will deposit first, and an element higher in the series (more negative) will deposit only when the solution is practically depleted of the ions of the first element.
