: :         乘吧？
: :         假設0.7V一個diode turn on的話
: :         串連應該會要兩倍電壓
: :         所以應該是1.4V turn on
: :         應該是要乘二吧？
: :         還是我想錯了？  XD
: 因為電壓源為１．５Vr
: 兩個串聯二極體導通
: 故每個為０．７５Vr
: 分壓加起來=電壓源為１．５Vr
: 只是我第二個二極體負載線不會劃
: 可以教我嗎

        ok, I see

        My answer is just for the I-V curve of two diodes.
        If you want to get a load-line of these two diodes in a specific
        applied voltage, you should do somethings:

        1. replot the I-V curve of diode with (1.5 Vr-V) as the x axis
        2. put the original curve of diode with the replotted one
        3. the intersection is the answer

推 l1l1l1l1:英文真好
推 Rigid:no, i still made some mistakes 'at applied voltage' XD
