\u00e9l\u00e9ment galvanique<\/strong><\/h2>\n

Introduction \u00e0:\u00a0<\/span>\u00a0<\/span><\/h2>\n

Production de voltage, r\u00e9action d’oxydor\u00e9duction, potentiel \u00e9lectrochimique, Luigi Galvani, Alessandro Volta\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

Mat\u00e9riel:\u00a0<\/span>\u00a0<\/span><\/h2>\n
    \n
  • clou ou vis galvanis\u00e9 \/ feuille de zinc \/ m\u00e9tal commun\u00a0<\/span>\u00a0<\/span><\/li>\n
  • Pi\u00e8ce de monnaie en cuivre \/ feuille de cuivre \/ m\u00e9tal pr\u00e9cieux\u00a0<\/span>\u00a0<\/span><\/li>\n
  • citron \/ fruit (orange, pamplemousse, pomme, etc.) \/ pomme de terre\u00a0<\/span>\u00a0<\/span><\/li>\n
  • voltm\u00e8tre \/ multim\u00e8tre\u00a0<\/span>\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

    + couteau de cuisine\u00a0<\/span>\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

    Montage:\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/h2>\n
      \n
    • Fais rouler le citron sur la table en exer\u00e7ant une l\u00e9g\u00e8re pression afin de d\u00e9truire partiellement la pulpe.\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Coupe-le en deux verticalement (par rapport \u00e0 l’axe en passant par les extr\u00e9mit\u00e9s).\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Plante le clou et la pi\u00e8ce de monnaie (\u00ab\u00a0\u00e9lectrodes\u00a0\u00bb) \u00e0 quelques centim\u00e8tres de distance dans le citron et relie-les au multim\u00e8tre.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      R\u00e9alisation:\u00a0<\/span>\u00a0<\/span><\/h2>\n

      Mesure la voltage \u00e9lectrique entre les \u00e9lectrodes ainsi que le courant de court-circuit.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

      Observation:\u00a0<\/span>\u00a0<\/span>\u00a0<\/span>\u00a0<\/span><\/h2>\n

      Il est possible de g\u00e9n\u00e9rer une voltage allant jusqu’\u00e0 0,9 V et une intensit\u00e9 de courant allant jusqu’\u00e0 environ 0,1 mA. <\/span>\u00a0<\/span><\/p>\n

      Conseils:\u00a0<\/span>\u00a0<\/span><\/h2>\n

      Il est possible de connecter plusieurs piles au citron en s\u00e9rie.<\/span>\u00a0<\/span><\/p>\n","protected":false},"featured_media":1337,"template":"","meta":[],"product_brand":[],"product_cat":[976,985,883,894,895],"product_tag":[],"class_list":{"0":"post-1336","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-2-voltage-courant","7":"product_cat-5-energie-puissance","8":"product_cat-b-electricite-fr","9":"product_cat-h-experiences-historiques-fr","10":"product_cat-i-appareils-physiques-fr","11":"","12":"woocommerce-text-align-left","13":"woocommerce-image-align-center","15":"first","16":"instock","17":"shipping-taxable","18":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product\/1336","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media\/1337"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media?parent=1336"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_brand?post=1336"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_cat?post=1336"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_tag?post=1336"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
