Trata-se de um método de investigação quase experimental que visa criar um dispositivo de temporização da tensão para proteção dos aparelhos eléctricos contra picos de energia devido a falhas de corrente a um custo acessível. A temperatura média para os três tratamentos em todas as réplicas foi normal, com base na temperatura máxima do contactor magnético, que é de 1000C. O dispositivo foi utilizado para o ensino de eletrónica, tendo o desempenho dos alunos melhorado com base nos resultados do pré-teste e do pós-teste. A fiabilidade do teste, com base no resultado do pós-teste, foi de 0,75, interpretada como boa, o que significa que o instrumento de avaliação é bom; no entanto, há provavelmente alguns itens que poderiam ser melhorados. Ao testar a hipótese de não haver correlação significativa entre o pré-teste e o pós-teste aos níveis de significância de 0,01 e 0,05, o investigador não conseguiu apresentar provas suficientes para aceitar a hipótese nula. Ficou estabelecido que o dispositivo de temporização da tensão é útil para o ensino da eletrónica. Recomenda-se que se siga o procedimento indicado no guia de instrução proposto para a tecnologia eletrónica que pode ser utilizada para comercialização.
