Assessment
Assessment
Avaliação teórico-prática (70%) - realização de 2 frequências no período de aulas, cada uma com peso de 40% na avaliação final ou avaliação por exame de recurso/especial com o valor de 80%. Esta componente tem nota mínima de 7 val. em 14 val.
Avaliação laboratorial (20%) - Avaliação da componente laboratorial através da realização de relatórios dos trabalhos práticos feitos em laboratório ou, em época de recurso/especial, através de um exame de laboratório. Esta componente tem nota mínima de 2 val. em 4 val.
Os temas dos trabalhos laboratoriais são:
1. Sistemas trifásicos
2. Análise de redes de energia.
A assiduidade e participação nas aulas será contabilizada com uma componente de 10% da nota final.
A realização de exame segue o regulamento geral de avaliação, sendo as inscrições obrigatórias.
Nota: Os resultados das avaliações cima descritas poderão sofrer correções através da realização de uma prova oral extraordinária que os alunos terão de realizar quando solicitado pelo docente
