Consider the Thevenin equivalent of the circuit below with respect to terminals a–b. The open circuit voltage across terminals a–b is: (1) 1 V (5) 1.5 V (2) 2 V (6) -2.5 V (3) 3 V (7) none of these 1Ω (4) 4 V 1Ω a ix 2ix + - 2Ω b Answer = #7 Problem 2. Consider the Thevenin equivalent of the circuit below with respect to terminals a–b. The Thevenin equivalent resistance seen at terminals a–b is: (1) 1 Ω (5) -2 Ω (2) 2 Ω (6) -1 Ω (3) 3 Ω (7) 2.5 Ω 1Ω (4) -3 Ω 1Ω a ix 2ix + - 2Ω b Answer = #3 2 Problem 3. The switch S1 in the circuit below opens at time t = 0 after having been closed for a very long time. Then switch S2 closes at time t = 2 msec. Find the energy supplied by the capacitor over the time interval 0 &lt; t &lt; ∞. (1) 200 µJ (5) 100 µJ (2) 250 µJ (6) 125 µJ t= 0 (3) 400 µJ (7) 100 µJ 500 Ω (4) 50 µJ 1 KΩ S...
