Eletrónica

Electrotechnics I, Electrotechnics II

Nas aulas teóricas é feita uma exposição de cada assunto complementada pela resolução de exercícios de aplicação dos conhecimentos adquiridos. As aulas de orientação tutorial, para além do atendimento pedagógico e o esclarecimento de dúvidas, são também complementadas com a resolução de exercícios. Nas aulas laboratoriais são realizados, em grupo, trabalhos práticos que visam a validação experimental dos conhecimentos adquiridos e a implementação de novos circuitos desenhados e projectados pelos alunos. Semanalmente são ainda disponibilizados na plataforma Moodle, testes online individuais que acompanham os conteúdos teóricos leccionados.
