Engr 260 -- Circuits & Devices Sample Test 3 Part 2: (Note: For Part 1, go to the class website.) 1. By means of the circuit below the voltage v C is to be brought to 13 V in 3 ms by closing S 1 , with S 2 kept open. The voltage v C is then to be kept at this constant value of 13 V by closing switch S 2 . Determine the values of the voltage V s and the resistor R to achieve these results. Ans: V s =50.16 V; R = 3.498 k Ω 2. The switch has been closed for a long time when it was opened at t=0. Find the voltage across the inductor for t>0. Ans: t e t v 6 10 15 20 ) ( × = V
