Currently we had a quiz for load line analysis,
the question was:
Determine the value of R for the circuit below that will result in the diode current of 10mA if E=7V. use approximate analysis method and graph.
I answered Idq=10mA, Id=11.25mA, and R=622ohms because of the statement in the problem as "result in the diode current" i assumed that idq is the current given.
then my instructor says that the answer (Idq)should be should be 9.1mA.
I am very confused because prior examination i found the same question at Electronic devices and circuit theory but in the book the term "use approximation method" was not mentioned.
I attached the capture of the question.
Am i right with my answer? what is the difference with approximation method?
pls help I dont know if I will defend my answer to my instructor.
