ayuda porfa, La impedancia eléctrica es la oposición al paso de la corriente eléctrica que circula a través de un conductor y se expresa utilizando números complejos. Si un gran circuito está formado por dos circuitos cuyas impedancias son z 1 = 3 - 4i ohmios y z 2 = 7 + 5i ohmios, ¿cuál es la impedancia total del gran circuito?
