Uma bateria ideal n\u00e3o possui resist\u00eancia interna. Entretanto, baterias reais apresentam resist\u00eancia interna disponibilizando uma tens\u00e3o efetiva V inferior \u00e0 sua tens\u00e3o nominal \u00a3, conforme a figura. Uma vez que se sabe o valor da tens\u00e3o nominal da bateria, determina-se sua carga pelo conhecimento da corrente i enquanto est\u00e1 conectada a um circuito de resist\u00eancia R, de tens\u00e3o efetiva V, e da resist\u00eancia interna r da bateria.<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" src=\"https:\/\/aws.explicae.com.br\/app\/uploads\/avatars\/1665214575213.png\" alt=\"\" style=\"width: 192px; height: 159.256px;\"\/><\/p>\n<p style=\"text-align: left; \">De posse de um volt\u00edmetro V , de um amper\u00edmetro A e\u00a0 de uma resist\u00eancia-teste R, a configura\u00e7\u00e3o adequada para avaliar a carga da bateria \u00e9:<\/p>\n<\/div>\n<ul class=\"question-options\">\n<li class=\"option-0\">\n<p>    <img decoding=\"async\" src=\"https:\/\/blogger.googleusercontent.com\/img\/a\/AVvXsEjQdEVIBGbXjmfICE40NJ1_JczBpJFVTG1w6xX18LMsDXmgCGiMUEP88aOl-G-3VS1hMfk9pbXSMrU7ESxnZWWFFvL4bRKw-QDEAle23HX_sRJR6M8bcUsvnM19kZcORGuuBoM4KDTnN8Pu3i26Rwo3iwXQ_TgdSljtx1xyQ5iWqENEXIGh4xojYNCF=s16000\" alt=\"enem 2021\"\/>    <\/p>\n<\/li>\n<li class=\"option-0\">\n<p>    <img decoding=\"async\" src=\"https:\/\/blogger.googleusercontent.com\/img\/a\/AVvXsEhkcs27eyCYsgZ5dxxX_vI8HuZCLJchXKggVq-iynvXGhtYU6bwHINhkvtalxFSQOFeC3DSi4shOA5rYbMmYRjgc3Qt7dWkiUevEPRWfzBwQbRjNSVWizfFG_9ic6bg88seMkUR4A-NWxdQpXTEjsg6OZZ9bm_7JBJQUnQFPhP7LYG4P6OCUdmBw6ed=s16000\" alt=\"enem 2021\"\/>    <\/p>\n<\/li>\n<li class=\"option-0\">\n<p>    <img decoding=\"async\" src=\"https:\/\/blogger.googleusercontent.com\/img\/a\/AVvXsEjmx8SS4LMItakZdSnAIOEHaV9_weKjcKe6nrwOStQw8bKus4llZRBvyAIJasr_mG1obAEpwegFsT5yWxj5TeQlQ0xVrM5oGgM4HLGnKAeBCY8L7YlUGW3jR8pb91lxC2DLOSy7RBDDzDPyWDWIlCMdx6sJ5GUN9yUy3f7_rGS6qR7UMY71uGT6wOBL=s16000\" alt=\"enem 2021\"\/>    <\/p>\n<\/li>\n<li class=\"option-0\">\n<p>    <img decoding=\"async\" src=\"https:\/\/blogger.googleusercontent.com\/img\/a\/AVvXsEi6fGo9fB8q8FicVN3E4XRH4NAJn7AMVxJsm7RsHA5eNGm4G6o2DS2GgK35JuDzMWpVTZs3mcCPIjV0e4t6oD3JcXfULWnsmk0U_WwJXt9st7KSP3flZGzl3r5hvtrIdFv8L1Pxifuynh-oVjm47Xn5RSRovMSXYT0ETgVgrJ2LstiCnROGqXHwOh29=s16000\" alt=\"enem 2021\"\/>    <\/p>\n<\/li>\n<li class=\"option-1\">\n<p>    <img decoding=\"async\" src=\"https:\/\/blogger.googleusercontent.com\/img\/a\/AVvXsEgwnK1L6dy7AkS-t392P3JzgyLeSq2pH335BsnxB2Y8BCMXtft89DYJi7Od2Ntd0VvqT6cbt01IG0met-Z0Kkud2wXX6KZhAdGLk35aZrEfIEWmglgkbcO1a7lqQjskxaXJKyaXtCe0HYcnZIxL-mWAB1I1QjVb6Q7mBVpOqPfIa5OhG6VY8nRPVBY6=s16000\" alt=\"enem 2021\"\/>    <\/p>\n<\/li>\n<\/ul>\n","protected":false},"featured_media":19139,"template":"","categories":[355,336,75,76],"_links":{"self":[{"href":"https:\/\/blog.explicae.com.br\/wp-json\/wp\/v2\/questao\/19138"}],"collection":[{"href":"https:\/\/blog.explicae.com.br\/wp-json\/wp\/v2\/questao"}],"about":[{"href":"https:\/\/blog.explicae.com.br\/wp-json\/wp\/v2\/types\/questao"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/blog.explicae.com.br\/wp-json\/wp\/v2\/media\/19139"}],"wp:attachment":[{"href":"https:\/\/blog.explicae.com.br\/wp-json\/wp\/v2\/media?parent=19138"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blog.explicae.com.br\/wp-json\/wp\/v2\/categories?post=19138"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
