🔊 O FREIO INVISÍVEL DA POTÊNCIA: COMO A IMPEDÂNCIA MUDA TUDO O amplificador informa 3.000 W, mas a potência entregue ao alto-falante pode mudar durante a reprodução. Isso acontece porque a impedância real não permanece fixa: ela varia conforme a frequência, a sintonia da caixa, o movimento do cone e o aquecimento da bobina. Neste vídeo, você vai entender por que dois sistemas com o mesmo módulo e o mesmo alto-falante podem apresentar resultados diferentes — e como medir tensão, corrente, impe
