Components:<\/h3>\n\n- \n
Pila<\/strong>: proporciona l’energia (la for\u00e7a electromotriu).<\/p>\n<\/li>\n- \n
Interruptor<\/strong>: obre o tanca el circuit.<\/p>\n<\/li>\n- \n
Bombeta<\/strong>: transforma l’energia el\u00e8ctrica en llum i calor.<\/p>\n<\/li>\n<\/ol>\n
\nCirculaci\u00f3 dels electrons:<\/h3>\n\n- \n
Quan l’interruptor est\u00e0 tancat (circuit tancat):<\/strong><\/p>\n\n- \n
Els electrons surten del pol negatiu de la pila<\/strong> (que \u00e9s on hi ha un exc\u00e9s d’electrons).<\/p>\n<\/li>\n- \n
Viatgen pel fil conductor fins arribar a la bombeta<\/strong>.<\/p>\n<\/li>\n- \n
En passar per la bombeta, els electrons cedeixen part de la seva energia<\/strong> a la resist\u00e8ncia interna de la bombeta, que es calenta i emet llum<\/strong>.<\/p>\n<\/li>\n- \n
Despr\u00e9s, continuen pel fil fins arribar al pol positiu de la pila<\/strong>.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n- \n
Quan l’interruptor est\u00e0 obert (circuit obert):<\/strong><\/p>\n\n- \n
El cam\u00ed est\u00e0 tallat, aix\u00ed que els electrons no poden circular<\/strong>, i la bombeta no s\u2019enc\u00e9n<\/strong>.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
\nImportant:<\/h3>\n\n- \n
El moviment dels electrons reals<\/strong> va del pol negatiu al pol positiu<\/strong> de la pila.<\/p>\n<\/li>\n- \n
Per\u00f2, tradicionalment, en els dibuixos i esquemes el\u00e8ctrics, es diu que el corrent el\u00e8ctric<\/strong> va del pol positiu al negatiu<\/strong> (aix\u00f2 es diu “corrent convencional”).<\/p>\n<\/li>\n<\/ul>\nAra anem al nostre cas.
