: : 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
: 感恩
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
