2) Determine the Resistor value
a)1.75k b) 2 k e) 2.5k d)2.285 k e) 5k
3) What is the ID quiescent value approximately in mA’s?
a) 2 mA b) 1.7 mA c) 1.5 mA d) 1 mA e) 0.6 mA
Homework Equations
V=IR
Id=(Vps/R)(Vd/R)
The Attempt at a Solution
I get Id=1.7 mA for part 3. I just found that by using the graph it looked liked 1.7 so thats what I assume is the answer. I think R can be found using the graph and ohms law Vd=5 V and I= 2 mA which gives R=2.5kΩ. What im wondering is why do I use the farthest values here? Why dont I use the Vd and Id values are where the lines cross? Vps=RId+Vd=2.5(1.7)+.75=5v for part 1 this can be found using KVL because I had already found R, Id, and Vd.
I uploaded the entire quiz and a picture so that you could see the graph
