Les voltm\u00e8tres, dispositifs essentiels \u00e0 cette fin, se divisent en deux cat\u00e9gories principales : les voltm\u00e8tres \u00e0 courant continu (CC) et ceux \u00e0 courant alternatif (CA). Chacun de ces instruments a des caract\u00e9ristiques et des applications sp\u00e9cifiques.<\/p>\n<h2>Volm\u00e8tre CC<\/h2>\n<p>Le voltm\u00e8tre CC est con\u00e7u pour mesurer la tension de courant continu. Il mesure la valeur de cr\u00eate de la tension CC. Ce type de voltm\u00e8tre ne n\u00e9cessite pas de redresseur avant un amplificateur multistage. La construction la plus courante de voltm\u00e8tre CC est le voltm\u00e8tre \u00e0 bobine mobile aimant permanent (PMMC), \u00e9galement connu sous le nom de compteur D&rsquo;Arsonval ou de galvanom\u00e8tre. Il d\u00e9termine la d\u00e9flexion angulaire dans un champ magn\u00e9tique uniforme pour indiquer le courant traversant la bobine.<\/p>\n<h2>Volm\u00e8tre CA<\/h2>\n<p>\u00c0 l&rsquo;inverse, le voltm\u00e8tre CA est utilis\u00e9 pour mesurer la tension de courant alternatif, mesurant la valeur efficace (RMS) de cette tension. Ce type de voltm\u00e8tre int\u00e8gre un redresseur avant l&rsquo;amplificateur. Parmi les types les plus courants, on trouve le voltm\u00e8tre \u00e0 fer mobile, utilis\u00e9 principalement pour mesurer les tensions et courants alternatifs. Dans ces instruments, le syst\u00e8me mobile se compose d&rsquo;un ou plusieurs morceaux de fer doux sp\u00e9cialement fa\u00e7onn\u00e9s, agissant sous l&rsquo;effet du courant dans la bobine.<\/p>\n<h2>Types de Volm\u00e8tres<\/h2>\n<ul>\n<li><strong>Volm\u00e8tre Num\u00e9rique (DVM)<\/strong> : Affiche les valeurs de tension CA et CC en chiffres discrets au lieu d&rsquo;une d\u00e9flexion de pointeur. Bas\u00e9 sur un convertisseur analogique-num\u00e9rique int\u00e9grant.<\/li>\n<li><strong>\u00c9lectrodynamom\u00e8tre<\/strong> : Utilis\u00e9 comme voltm\u00e8tres et amp\u00e8rem\u00e8tres CA dans les gammes de fr\u00e9quences de puissance et la partie inf\u00e9rieure de la gamme de fr\u00e9quences audio.<\/li>\n<li><strong>Volm\u00e8tre \u00e0 Rectification<\/strong> : Convertit le courant alternatif en courant continu. Utilis\u00e9 pour mesurer les tensions CA et CC.<\/li>\n<li><strong>Volm\u00e8tre \u00e0 Induction<\/strong> : Fonctionne sur le principe de l&rsquo;induction mutuelle, mesurant uniquement la puissance CA.<\/li>\n<li><strong>Volm\u00e8tre \u00c9lectrostatique<\/strong> : Mesure directement la tension sans effet de courant. Utilis\u00e9 pour mesurer de grandes tensions \u00e9lectriques sans contact physique.<\/li>\n<\/ul>\n<h2>Diff\u00e9rences Cl\u00e9s<\/h2>\n<p>La distinction majeure entre les voltm\u00e8tres CC et CA r\u00e9side dans leurs applications sp\u00e9cifiques : le voltm\u00e8tre CC pour la tension continue et le voltm\u00e8tre CA pour la tension alternative. De plus, la conception et le principe de fonctionnement diff\u00e8rent entre les deux, influen\u00e7ant leur pr\u00e9cision et leur domaine d&rsquo;application.<\/p>\n<h2>Conclusion<\/h2>\n<p>La compr\u00e9hension des voltm\u00e8tres CC et CA est cruciale pour les professionnels et les passionn\u00e9s d&rsquo;\u00e9lectricit\u00e9. Chaque type poss\u00e8de des caract\u00e9ristiques uniques adapt\u00e9es \u00e0 des mesures sp\u00e9cifiques, rendant leur utilisation appropri\u00e9e indispensable dans divers contextes de mesure de tension.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.electricity-magnetism.org\/wp-content\/uploads\/2022\/07\/AC-DC-voltmeter.png\" alt=\"DC and AC Voltmeter\" \/><\/p>\n<div style=\"text-align: center; font-size: 20px;\">\n    <a href=\"https:\/\/www.electricity-magnetism.org\/voltmeter\/dc-and-ac-voltmeter\/\">Original Article<\/a>\n<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Le voltm\u00e8tre DC est utilis\u00e9 pour mesurer la tension DC, tandis que le voltm\u00e8tre AC est utilis\u00e9 pour mesurer la tension AC.
