Questions 1-2: 10 points each, Question 3-5: 12 points Max=56l50 points (6 bonus points) Part A: (Hand in Separately!) 1. Find the equivalent capacitance. Show all intermediate circuits and calculations clearl . y 6 F H F Name: 2. Find a Thevenin equivalent circuit. Show all intermediate circuits and calculations. Name: 3. Solve using superposition (killing all but one source at a time). Draw appropriate circuit diagrams. Find i. i. UL “V a LA. “UL a Pile B (Hand in separately!) Name: 4. (a) Write nodal equations. Note the dependent source. Note also that the resistors are labeled with their conductances (inverse resistance in Siemens). (b) Simplify the equations. Solve the equations for v1 and v2 using determinants. Show steps. Name: 5. At time 0 the switch opens. Prior to time 0 the switch was closed for a long time. a. Fund vc(0-) and i(0-). Show any calculations. Draw a circuit diagram. b. Find vc(0+) and i(0+). Show any calculations. Draw a circuit diagram. c. What are the values of vC and I as time goes to inﬁnity (switch open for a very long time)?
