: : 乘吧？
: : 假设0.7V一个diode turn on的话
: : 串连应该会要两倍电压
: : 所以应该是1.4V turn on
: : 应该是要乘二吧？
: : 还是我想错了？ XD
: 因为电压源为１．５Vr
: 两个串联二极体导通
: 故每个为０．７５Vr
: 分压加起来=电压源为１．５Vr
: 只是我第二个二极体负载线不会划
: 可以教我吗
: 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
