A steel-hulled ship in sea water produces an electric field around itself. The source of this field are electrochemical processes and ship's cathodic protection. The analysis of the electric field around the ship is important by the reason of the ship's identification and counter-mine protection. The paper presents a simplified model of the ship's multisource electric field, which allows to calculate the electric field distribution...

Sources have been described of corrosively hazardous electric fields and methods of determination of the corrosion hazard to metal structures caused by electrolytic corrosion. Results of potential and impedance investigations in the field of stray currents flowing out of a tram traction and in the presence of a defined electric field of low frequency have been presented. Uncertainties have been indicated relating to the generally...

A designed assembly of particles at liquid interfaces offers many advantages for development of materials, and can be performed by various means. Electric fields provide a flexible method for structuring particles on drops, utilizing electrohydrodynamic circulation flows, and dielectrophoretic and electrophoretic interactions. In addition to the properties of the applied electric field, the manipulation of particles often depends...

Badano wpływ zewnętrznego pola elektrycznego na prawdopodobieństwo rekombinacji nośników ładunku w molekularnych ciałach stałych. Przybliżenie analityczne wykazuje, że prawdopodobieństwo to maleje ze wzrostem pola elektrycznego. Otrzymane wyniki mogą być pomocne w wyjaśnieniu spadku wydajności elektroluminescencji w jednowarstwowych diodach elektroluminescencyjnych w zakresie wysokich pól elektrycznych.

The paper presents an analytical approach to the perturbation analysis of electric field distribution caused by a sphere and an ellipsoid placed in a uniform electric field.
