It is demonstrated that in these conditions, the effective conductivity of polyelectrolyte is the linear function of     n \u2299    . This happens due to the change of the electric field in the polyelectrolyte under the effect of colloidal particle polarization. The proposed theory explains the recent experimental findings and presents the alternative to mean spherical approximation which predicts the nonlinear I\u2013V characteristics of dilute colloidal polyelectrolytes due to entropy changes.<\/jats:p>","DOI":"10.3390\/e22020225","type":"journal-article","created":{"date-parts":[[2020,2,18]],"date-time":"2020-02-18T10:10:25Z","timestamp":1582020625000},"page":"225","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The Ohm Law as an Alternative for the Entropy Origin Nonlinearities in Conductivity of Dilute Colloidal Polyelectrolytes"],"prefix":"10.3390","volume":"22","author":[{"given":"Ioulia","family":"Chikina","sequence":"first","affiliation":[{"name":"LIONS, NIMBE, CEA, CNRS, Universit\u00e8 Paris-Saclay, CEA Saclay, 91191 Gif-sur-Yvette, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valeri","family":"Shikin","sequence":"additional","affiliation":[{"name":"ISSP, RAS, Chernogolovka, 142432 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrey","family":"Varlamov","sequence":"additional","affiliation":[{"name":"CNR-SPIN, c\/o DICII-Universit\u00e1 di Roma Tor Vergata, Via del Politecnico, 1, 00133 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1463","DOI":"10.1080\/00268976.2014.906672","article-title":"Influence of the volume fraction on the electrokinetic properties of maghemite nanoparticles in suspension","volume":"112","author":"Lucas","year":"2014","journal-title":"Mol.
