#4. D1 V1 ++ D2 ++ 10 Ohms -5 Vdc 0 For the silicon diodes shown, the reverse saturation currents are 2 nA and 20 nA, for germanium Diode 1 and silicon Diode 2, respectively, at 300 K. diodes. V1 negative 5 Volts. Given that both diodes are reverse biased, find; a) the value of the voltage across each diode, and b) the voltage across the resistor. Note: Diodes are not ideal
