Problem 3: /20 In the circuit shown below, the switch has been closed at position B for a long time before closing at position A at t = 0. t=0 AB 2 A + 50Ω in(t) 2.5 μF ic(t) 20mH ir (t) a) Calculate a and wo and determine if the circuit is overdamped, critically-damped, or underdamped. (4 points) b) Analyze the circuit at t= 0 and determine v(0¯), iR(0¯), iL(0), and ic(07). (4 points) c) Analyze the circuit at t= 0 and determine v(0*), ir(0*), iL(0¹), and ic(0*). (4 points) d) Determine an expression for v(t) and i(t) valid for all t≥ 0¹. (4 points) e) Simulate the circuit for t≥ 0 using LTspice XVII and verify that your analytical solutions match those of the simulations. (4 points)
