A blue LED is connected across a two-terminal source whose Thvenin equivalent is (v_{mathrm{T}}=3 mathrm{~V}) and (R_{mathrm{T}}=10

Question:

A blue LED is connected across a two-terminal source whose Thévenin equivalent is $v_{\mathrm{T}}=3 \mathrm{~V}$ and $R_{\mathrm{T}}=10 \Omega$. The $i-v$ characteristic of the LED is $i=10^{-12}\left(e^{10 v}-1ight)$. Figure P $_{3}=54$ shows the LED's $i-v$ characteristic. Using either MATLAB or a graphical approach, determine the voltage across and current through the LED.
