    The circuit is a normal series circuit with a voltage source, a photodiode and a Resistor.
    We have to plot the dc load line. the question states: "The cicruit uses a photo diode with the illumination characteristics such that when the device is operated with reverse voltage it operates as a photoconductive device and when operating without the reverse voltage, it operates as a photo voltaic device. Plot the Dc load line.
    Voltage source (E)=1.5V, R1 = 220 ohm and Vd=0.5V

    This is what ive found in a book.

    Can anybody help me in finding the points either at A or B which I have marked with the red circles. Im assuming that is what I need to plot?
