Question

R1 + VC- 35u(-t) 3u(t) Assume R1 = 20, R2 = 30, and C = 0.33F. What is the steady-state value of VC (in V) for t<0s? Points possible: 1 Allowed attempts: 3 Retry penalty: 33.333% Find the Thevenin equivalent of the circuit about the capacitor fort > 0. Assume the Thevenin equivalent voltage is defined so its negative terminal would be connected to the negative terminal of VC- What is RTH (in )? Points possible: 1 Allowed attempts: 3 Retry penalty: 33.333% What is VTH (in V)? Points possible: 1 Allowed attempts: 3 Retry penalty: 33.333% What is ic(0+) (in A), the capacitor current immediately after t = 0? Remember that by default, ic is assumed to be passive to vc. Hint: You have the Thevenin equivalent of the circuit, so use it to find ic instead of solving for ic in the original circuit... Points possible: 1 Allowed attempts: 3 Retry penalty: 33.333% What is vC(45) (in V), the capacitor voltage at t = 45? Points possible: 1 Allowed attempts: 3 Retry penalty: 33.333% What is ic(4) (in A), the capacitor current at t = 4s?
