Assume that the diode in Figure P8.9 requires a minimum current of 1 mA to be above the knee of its i-v characteristic.

a. What should be the value of R to establish 5 mA in the circuit?

b. With the value of R determined in part a, what is the minimum value to which the voltage E could be reduced and still maintain diode current above the knee? Use Vγ = 0.7 V.
