An arc welding process that uses an arc between a continuous filler metal electrode and the weld pool, employing approximately vertical welding progression with backing to confine the molten weld metal.

An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water.

An electrolytic cell is an electrochemical cell that uses electrical energy to drive a non-spontaneous redox reaction. It is often used to decompose chemical compounds, in a process called electrolysis.

The method of surface preparation which can be used for ballast tanks before drydocking. It bases on a breakdown of the rust using very strong electrical current.

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Electromagnetic compatibility is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference or even physical damage in operational equipment.

An electromagnetic field is a classical field produced by accelerating electric charges.

Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field.

An electromagnetic pulse also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy.

An electromagnetic pump is a pump that moves liquid metal (or any electrically conductive liquid) using electromagnetism.

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy.

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

Electromechanics focuses on the interaction of electrical and mechanical systems as a whole and how the two systems interact with each other.

An electrometer is an electrical instrument for measuring electric charge or electrical potential difference.

Electromethanogenesis is a form of electrofuel production where methane is produced by direct biological conversion of electrical current and carbon dioxide.

In electromagnetism and electronics, electromotive force is the electrical action produced by a non-electrical source.

The electron is a subatomic particle whose electric charge is negative one elementary charge.

The newly developed navigational tool using digital charts (vectorised and raster charts) for navigational tasks normally carried out with paper charts. The equipment must be type-approved and uses up-to-date official charts.

Vector charts made up of layers which can be displayed selectively. Each point on the chart is digitally mapped, allowing information to be used in a more detailed way, such as clicking on a feature to display its information.

The electronic–hydraulic analogy is the most widely used analogy for "electron fluid" in a metal conductor.
