3–71 A blue LED is connected across a two-terminal source whose Thévenin equivalent is vT = 3 V and RT =10 Ω. The i – v characteristic of the LED is i=10^‒12 (e^10v ‒ 1).

Figure P3−71 shows the LED’s i – v characteristic. Using either MATLAB or a graphical approach, determine the voltage across and current through the LED
