(a) Identify the essential nodes. (5 pts)
(b) Identify the 'Rule #0' nodes. Derive an expression for each 'Rule #0' node
voltage. (5 pts)
(c) Employing nodal analysis, derive an expression for all essential node voltages
(excluding 'Rule #0' nodes). (20 pts)
(d) Employing nodal analysis, derive an expression for any non-essential node
voltages (excluding 'Rule #0' nodes). (10 pts)
(e) Calculate a value for $V_1$, $V_2$, and $V_3$. Assume that $R_1 = 3 k\Omega$, $R_2 = 6 k\Omega$, $R_3 = 5 k\Omega$,
$I_{G1} = 56.6667 \mu A$, and $V_{G2} = 100 mV$. (10 pts)
(f) Calculate a value for $I_{R3}$ (flowing from $V_3$ to $V_2$). (10 pts)
