Question 2 of EEE20002 Quiz 2 is on the analysis of the first order RC circuit...
I’m in hurry please Question2 0.75 pts It is known that R1-R2-R3-1 ㏀、С-1500 mF and Vs 1 2 V for the RC circuit in Figure 2.2. where the switch was open for a long time and is closed at t -O sec 1 R1V2 Vc Ic Switch Vs 12 R2 Figure 2.2 The voltage V2tt) at t -1.0 sec is most approximate to 8.32 V 1.64 V 6.74 V 3.37 V
2 First-Order RC Circuit: Natural Response The switch in the circuit in Figure 2 has been in position for a long time. At t = 0, the switch moves to position (the switch opens) and stays there. Assuming that V. > O for the constant voltage source, (a) find vc(0-), vc(0+), ic(0-), and ic(0+); (b) find vc(t) when t 20 (if you want, you can write vo(t) by circuit inspection; you don't need to show the differential equation); and (c)...
Question 1 Given the following information about a 2nd order transient circuit, solve for the coefficient an in the capacitor voltage + vc (0)for t>0. : (t) = e sunt Uc * (asje**v2= ext/85) + a2e C = 4 mF Vcl0+) = 2v Vc(infinity) = 5 V ic(0+) = 5 A Wo = 46 rad/sec zeta = 2.72
