Find Id(current drain) and Vd(voltage drain) for the current-source biased JFET in Figure 4-79 . Also if you can let me know how much per question.

15. Find Id(current drain) and Vd(voltage drain) for the current-source biased JFET in Figure 4-79 . Also if you can let me know how much per question. In the past I haven't got any help. Because i have more questions. I have to do number fifth-teen through twenty-six (15-26) . This is for Solid States Devices ET1310 at Itt-Tech in Colorado
