Solve the below:
Q: In the circuit shown in Fig. P4.30, D1 is a large-area, high-current diode whose reverse leakage is high and independent of applied voltage, while D2 is a much smaller, low-current diode. At an ambient temperature of 20°C, resistorR1 is adjusted to makeVR1 =V2 =520 mV. Subsequent measurement indicates that R1 is 520 k_. What do you expect the voltages VR1 and V2 to become at 0°C and at 40°C?
