MANOS ME AJUDEM COM ESSA QUESTÂO JA TO DUAS HORAS NELA Os motores elétricos comportam-se como receptores que utilizam a tensão para realizar trabalho. No entanto, como nos geradores, eles aquecem devido ao efeito joule. Imagine um motor que, quando em funcionamento, dissipa 8 W e tem uma força contraeletromotriz (fcem) de 12 V. Considerando estas informações e os estudos desenvolvidos sobre os receptores. Qual a resistência interna desse motor quando ligado a uma tensão de15 V
