1) (5 pts) Use node voltage analysis at nodes A and B to determine values for VA, VB, I₁, 12 and 13.
If a current has a negative value, then the reference direction chosen was incorrect and the current
is positive in the opposite direction. Your answer can be the negative value – i.e. you find that 12 =
-1mA. Note, the current through R5 is (VB - 28 Volts)/10K

2) (5pts) Use node voltage analysis to find values for the node voltages VA, VR and Vc. Use these
node voltages to determine values for V1, V2, V3, V4, 11, 12, 13, and 14. Hints: V3 = VB and the value
for Vc can be found with no analysis. Dependent current source has a value of gV3 amps

Hint: use KCL to find Ic in terms of la and lb, use KVL around the right loop to find a relationship
between la and lb, use KVL around the outer loop to solve for a current value (use ohms law for
the voltage drops across the resistors)

2) (5 pts) For problem 1, show that the power supplied (delivered) by the source equals the
power absorbed by the resistors.
3) (5 pts) Determine the equivalent resistance looking into terminals a-b for the two circuits
shown. Use series and parallel resistor combinations. Hint: work from the opposite end of
terminals a-b towards terminals a-b
