Question

A pn junction diode is in series with a 100 kΩ  resistor and a 3.5 V power supply. The reverse-saturation

current of the diode is IS = 5 nA. (a) Determine the diode current and voltage if the diode is forward biased. (b) Repart part (a) if the diode is reverse biased (connection flipped). Assume VT = 26 mV at room temperature.
