Pour mesurer le courant dans un fil, il est souvent n\u00e9cessaire de couper ou de briser le fil et d&rsquo;ins\u00e9rer l&rsquo;amp\u00e8rem\u00e8tre de mani\u00e8re \u00e0 ce que le courant mesur\u00e9 passe \u00e0 travers l&rsquo;appareil. Un ampm\u00e8tre mesure toujours le courant qui le traverse. Id\u00e9alement, un ampm\u00e8tre aurait une r\u00e9sistance nulle, \u00e9vitant ainsi d&rsquo;affecter le courant dans la branche du circuit o\u00f9 il est ins\u00e9r\u00e9. Cependant, les ampm\u00e8tres r\u00e9els pr\u00e9sentent toujours une certaine r\u00e9sistance, bien qu&rsquo;il soit souhaitable que cette r\u00e9sistance soit la plus faible possible.<\/p>\n<h2>Applications des Amp\u00e8rem\u00e8tres<\/h2>\n<p>Les ampm\u00e8tres sont utilis\u00e9s dans diverses applications pour mesurer le courant \u00e9lectrique.
