3-5. For the following circuit, answer the questions. For these problems, you may need a calculator. Assume that the circuit was initially in steady state and the capacitor was originally discharged. 1kOhm ow 1kOhm M 1kOhm W Closed at t=0 0.5mH 000 1.5k Ohm + 1V + 1V 1mA 2kOhm w S1 S2 V(t) + + *E HH w 2kOhm 1V 3mA 2V + 2nF
3. S1 and S2 are always open. Calculate and sketch v(t) for t>0. Mark the values of v(t) on the sketch when t= 0.5 us, 1 us, 1.5 us, and 2 us. [1] 4. S1 is always closed while S2 is always open. Calculate and sketch v(t) for t>0. Mark the values of v(t) on the sketch when t= 0.511 us, 11 us, 1.511 us, and 21 us. [1] 5. S1 is always open. S2 is always closed. Calculate and sketch v(t) for t>0. Mark the values 5 15 20 of v(t) on the sketch when t= n us, 10 π μs, 8 - π μs, and π μs. [1] 8 8 8
