For the above circuit, assume $V_1 = 10V$, $V_2 = 5V$, and $R_1 = 4\Omega$, $R_2 = 2\Omega$, $R_3 = 2\Omega$, $R_4 = 3\Omega$. Assume
diodes D1 and D2 have the IV characteristics shown above.
A) Based on the IV characterstic plots, what are the cut-off voltages of D1 and D2 in units of [V]? (2pts)
B) Assume that D1 is ON and D2 is OFF. Find the voltages ($V_{D1}$ and $V_{D2}$) across the two diodes in units
of [V] and the currents ($I_{D1}$ and $I_{D2}$) flowing through the diodes in units of [A]. (10pts)
C) Was the assumption of the diodes' states in Part B correct? (1pts)
D) Assume that both D1 and D2 are ON. Find the voltages ($V_{D1}$ and $V_{D2}$) across the two diodes in units
of [V] and the currents ($I_{D1}$ and $I_{D2}$) flowing through the diodes in units of [A]. (10pts)
E) Was the assumption of the diodes' states in Part D correct? (1pts)
