Testando uma válvula EZ81 com 6,3V
2 years ago
1
Uma válvula rectificadora EZ81 a ser testada com uma tensão de alimentação de apenas 6,3V. Nota-se uma queda de tensão significativa através da válvula, se bem que ainda passa corrente suficiente para acender os LEDs. Os resistores não são necessários, e só servem como medida de protecção adicional para os LEDs.
